In the C Programming Language, thefabs functionreturns the absolute value of a floating-point number. Syntax The syntax for the fabs function in the C Language is: double fabs(double x); Parameters or Arguments
The result of a single-precision floating-point operation involving one or more input NaNs is the quiet NaN of bit pattern 0x7fffffff; Double-precision floating-point absolute value and negation are not compliant with IEEE-754 with respect to NaNs; these are passed through unchanged; Code mus...
