NAME
frexp, ldexp, modf - split into mantissa and exponent
SYNOPSIS
double frexp (value, eptr)
double value;
int *eptr;
double ldexp(value, exp)
double value;
double modf (value, iptr)
double value, *iptr;
DESCRIPTION
frexp
returns the mantissa of a double
value
as a double quantity,
x,
of maginitude less than 1 and stores an integer
n
such that
value = x*2**n inderectly through
eptr.
ldexp
returns the quantity
value*2**exp.
modf
returns the positive fractional part of
value
and stores the integer part indirectly through
lptr.
