19 Math::BigInt::FastCalc inherits from Math::BigInt::Calc.
20
21 Provides support for big integer calculations. Not intended to be used
22 by other modules. Other modules which sport the same functions can also
23 be used to support Math::BigInt, like Math::BigInt::GMP or
24 Math::BigInt::Pari.
25
26 In order to allow for multiple big integer libraries, Math::BigInt was
27 rewritten to use library modules for core math routines. Any module
28 which follows the same API as this can be used instead by using the
29 following:
30
31 use Math::BigInt lib => 'libname';
32
33 'libname' is either the long name ('Math::BigInt::Pari'), or only the
34 short version like 'Pari'. To use this library:
35
36 use Math::BigInt lib => 'FastCalc';
37
38 The default behaviour is to chose the best internal representation of
39 big integers, but the base length used in the internal representation
40 can be specified explicitly. Note that this must be done before
41 Math::BigInt is loaded. For example,
42
43 use Math::BigInt::FastCalc base_len => 3;
44 use Math::BigInt lib => 'FastCalc';
45
47 Math::BigInt::FastCalc works exactly like Math::BigInt::Calc. Numbers
48 are stored in decimal form chopped into parts.
49
51 The following functions are now implemented in FastCalc.xs:
52
53 _is_odd _is_even _is_one _is_zero
54 _is_two _is_ten
55 _zero _one _two _ten
56 _acmp _len
57 _inc _dec
58 __strip_zeros _copy

98 Separated from Math::BigInt and shaped API with the help of John
99 Peacock.
