NAME

6       frexp, ldexp, modf - split into mantissa and exponent

SYNOPSIS

9       double frexp(value, eptr)
10       double value;
11       int *eptr;
12
13       double ldexp(value, exp)
14       double value;
15
16       double modf(value, iptr)
17       double value, *iptr;
18

DESCRIPTION

20       Frexp  returns  the mantissa of a double value as a double quantity, x,
21       of magnitude less than 1 and stores an integer  n  such  that  value  =
22       x*2**n indirectly through eptr.
23
24       Ldexp returns the quantity value*2**exp.
25
26       Modf returns the positive fractional part of value and stores the inte‐
27       ger part indirectly through iptr.
