NAME
fdim, fdimf, fdiml - compute positive difference between two floating-point numbers
SYNOPSIS
cc [ flag... ] file... -lm [ library... ] #include <math.h> double fdim(double x, double y); float fdimf(float x, float y); long double fdiml(long double x, long double y);
DESCRIPTION
These functions determine the positive difference between their arguments. If x is greater than y, x-y is returned. If x is less than or equal to y, +0 is returned.
RETURN VALUES
Upon successful completion, these functions return the positive difference value. If x-y is positive and overflows, a range error occurs and fdim(), fdimf(), and fdiml() returns the value of the macro HUGE_VAL, HUGE_VALF, and HUGE_VALL, respectively. If x or y is NaN, a NaN is returned.
ERRORS
These functions will fail if: Range Error The result overflows. If the integer expression (math_errhandling & MATH_ERREXCEPT) is non-zero, the overflow floating-point exception will be raised.
USAGE
An application wanting to check for exceptions should call feclearexcept(FE_ALL_EXCEPT) before calling these functions. On return, if fetestexcept(FE_INVALID | FE_DIVBYZERO | FE_OVERFLOW | FE_UNDERFLOW) is non-zero, an exception has been raised. An application should either examine the return value or check the floating point exception flags to detect exceptions.
