FREXP(2)			       System Calls Manual				 FREXP(2)

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

SYNOPSIS
       #include <u.h>
       #include <libc.h>

       double frexp(double value, int *eptr)

       double ldexp(double value, int exp)

       double modf(double value, double *iptr)

DESCRIPTION
       Frexp  returns  the  mantissa of value and stores the exponent indirectly through eptr, so
       that value = frexp(value)*2**(*eptr).

       Ldexp returns the quantity value*2**exp.

       Modf returns the positive fractional part of value and stores the integer part  indirectly
       through iptr.

SOURCE
       /sys/src/libc/$objtype/frexp.c

SEE ALSO

DIAGNOSTICS
       Ldexp returns 0 for underflow and the appropriately signed infinity for overflow.
