21
22       val zero : nativeint
23
24       The native integer 0.
25
26
27
28       val one : nativeint
29
30       The native integer 1.
31

35
36       The native integer -1.

38
39
40       val neg : nativeint -> nativeint
41
42       Unary negation.
43
44
45
46       val add : nativeint -> nativeint -> nativeint
47
48       Addition.
49
50
51
52       val sub : nativeint -> nativeint -> nativeint
53
54       Subtraction.
55
56
57
58       val mul : nativeint -> nativeint -> nativeint
59
60       Multiplication.
61
62
63
64       val div : nativeint -> nativeint -> nativeint
65
66       Integer  division.  This division rounds the real quotient of its argu‐
67       ments towards zero, as specified for (/) .
68
69
70       Raises Division_by_zero if the second argument is zero.
71
72
73
74       val unsigned_div : nativeint -> nativeint -> nativeint
75
76       Same as Nativeint.div , except that arguments  and  result  are  inter‐
77       preted as     unsigned native integers.

80       Since 4.08.0
81
82
83
84       val rem : nativeint -> nativeint -> nativeint
85
86       Integer  remainder.   If y is not zero, the result of Nativeint.rem x y
87       satisfies the following properties: Nativeint.zero <= Nativeint.rem x y
88       < Nativeint.abs y and x = Nativeint.add (Nativeint.mul (Nativeint.div x
89       y) y)
90                             (Nativeint.rem x y) .  If y = 0 , Nativeint.rem x
91       y raises Division_by_zero .
92
93
94
95       val unsigned_rem : nativeint -> nativeint -> nativeint
96
97       Same  as  Nativeint.rem  ,  except that arguments and result are inter‐
98       preted as     unsigned native integers.

101       Since 4.08.0
102
103
104
105       val succ : nativeint -> nativeint
106
107       Successor.  Nativeint.succ x is Nativeint.add x Nativeint.one .
108
109
110
111       val pred : nativeint -> nativeint
112
113       Predecessor.  Nativeint.pred x is Nativeint.sub x Nativeint.one .
114

116
117       val abs : nativeint -> nativeint
118
119       Return the absolute value of its argument.
120
121
122
123       val size : int
124
125       The size in bits of a native integer.  This is equal to 32 on a  32-bit
126       platform and to 64 on a 64-bit platform.
127
128
129
130       val max_int : nativeint
131
132       The  greatest representable native integer, either 2^31 - 1 on a 32-bit
133       platform, or 2^63 - 1 on a 64-bit platform.
134
135
136
137       val min_int : nativeint
138
139       The smallest representable native integer, either  -2^31  on  a  32-bit
140       platform, or -2^63 on a 64-bit platform.
141
142
143
144       val logand : nativeint -> nativeint -> nativeint
145
146       Bitwise logical and.
147
148
149
150       val logor : nativeint -> nativeint -> nativeint
151
152       Bitwise logical or.
153
154
155
156       val logxor : nativeint -> nativeint -> nativeint
157
158       Bitwise logical exclusive or.
159
160
161
162       val lognot : nativeint -> nativeint
163
164       Bitwise logical negation.
165
166
167
168       val shift_left : nativeint -> int -> nativeint
169
170
171       Nativeint.shift_left x y shifts x to the left by y bits.  The result is
172       unspecified if y < 0 or y >= bitsize , where bitsize is 32 on a  32-bit
173       platform and 64 on a 64-bit platform.
174
175
176
177       val shift_right : nativeint -> int -> nativeint
178
179
180       Nativeint.shift_right  x y shifts x to the right by y bits.  This is an
181       arithmetic shift: the sign bit of x is replicated and inserted  in  the
182       vacated bits.  The result is unspecified if y < 0 or y >= bitsize .
183
184
185
186       val shift_right_logical : nativeint -> int -> nativeint
187
188
189       Nativeint.shift_right_logical  x  y  shifts  x  to the right by y bits.
190       This is a logical shift: zeroes are inserted in the  vacated  bits  re‐
191       gardless of the sign of x .  The result is unspecified if y < 0 or y >=
192       bitsize .
193
194
195
196       val of_int : int -> nativeint
197
198       Convert the given integer (type int ) to a  native  integer  (type  na‐
199       tiveint ).
200
201
202
203       val to_int : nativeint -> int
204
205       Convert  the given native integer (type nativeint ) to an integer (type
206       int ).  The high-order bit is lost during the conversion.
207
208
209
210       val unsigned_to_int : nativeint -> int option
211
212       Same as Nativeint.to_int , but interprets the argument as  an  unsigned
213       integer.  Returns None if the unsigned value of the argument cannot fit
214       into an int .
215
216
217       Since 4.08.0
218
219
220
221       val of_float : float -> nativeint
222
223       Convert the given floating-point number to a native integer, discarding
224       the fractional part (truncate towards 0).  The result of the conversion
225       is undefined if, after truncation, the number is outside  the  range  [
226       Nativeint.min_int , Nativeint.max_int ].
227
228
229
230       val to_float : nativeint -> float
231
232       Convert the given native integer to a floating-point number.
233
234
235
236       val of_int32 : int32 -> nativeint
237
238       Convert the given 32-bit integer (type int32 ) to a native integer.
239
240
241
242       val to_int32 : nativeint -> int32
243
244       Convert the given native integer to a 32-bit integer (type int32 ).  On
245       64-bit platforms, the 64-bit native integer is taken modulo 2^32,  i.e.
246       the  top  32 bits are lost.  On 32-bit platforms, the conversion is ex‐
247       act.
248
249
250
251       val of_string : string -> nativeint
252
253       Convert the given string to a native integer.  The string  is  read  in
254       decimal  (by default, or if the string begins with 0u ) or in hexadeci‐
255       mal, octal or binary if the string begins with 0x , 0o  or  0b  respec‐
256       tively.
257
258       The  0u  prefix reads the input as an unsigned integer in the range [0,
259       2*Nativeint.max_int+1] .  If the input exceeds Nativeint.max_int it  is
260       converted   to   the   signed  integer  Int64.min_int  +  input  -  Na‐
261       tiveint.max_int - 1 .
262
263
264       Raises Failure if the given string is not a valid representation of  an
265       integer,  or  if  the integer represented exceeds the range of integers
266       representable in type nativeint .
267
268
269
270       val of_string_opt : string -> nativeint option
271
272       Same as of_string , but return None instead of raising.
273
274
275       Since 4.05
276
277
278
279       val to_string : nativeint -> string
280
281       Return the string representation of its argument, in decimal.
282
283
284       type t = nativeint
285
286
287       An alias for the type of native integers.
288
289
290
291       val compare : t -> t -> int
292
293       The comparison function for native integers, with the  same  specifica‐
294       tion as compare .  Along with the type t , this function compare allows
295       the module Nativeint to be passed as argument to the functors  Set.Make
296       and Map.Make .
297
298
299
300       val unsigned_compare : t -> t -> int
301
302       Same  as  Nativeint.compare  , except that arguments are interpreted as
303       unsigned native integers.
304
305
306       Since 4.08.0
307
308
309
310       val equal : t -> t -> bool
311
312       The equal function for native ints.
