NAME
modf, modff, modfl - decompose floating-point number
SYNOPSIS
cc [ flag... ] file... -lm [ library... ] #include <math.h> double modf(double x, double *iptr); float modff(float x, float *iptr); long double modfl(long double x, long double *iptr);
DESCRIPTION
These functions break the argument x into integral and fractional parts, each of which has the same sign as the argument. It stores the integral part as a double for the modf() function, a float for the modff() function, or a long double for themodfl() function in the object pointed to by iptr.
RETURN VALUES
Upon successful completion, these functions return the signed fractional part of x. If x is NaN, a NaN is returned and *iptr is set to NaN. If x is +-Inf, +-0 is returned and *iptr is set to +-Inf.
ERRORS
No errors are defined.
USAGE
These functions compute the function result and *iptr such that: a = modf(x, &iptr) ; x == a+*iptr ;
