fmax, fmaxf, fmaxl

Defined in header <math.h> 
float       fmaxf( float x, float y );
+		 (1) (since C99) 
double      fmax( double x, double y );
+		 (2) (since C99) 
long double fmaxl( long double x, long double y );
+		 (3) (since C99)
Defined in header <tgmath.h> 
#define fmax( x, y )
+		 (4) (since C99)
+1-3) Returns the larger of two floating point arguments, treating NaNs as missing data (between a NaN and a numeric value, the numeric value is chosen).
+4) Type-generic macro: If any argument has type long double, fmaxl is called. Otherwise, if any argument has integer type or has type double, fmax is called. Otherwise, fmaxf is called.

Parameters

+ +
x, y - floating point values

Return value

If successful, returns the larger of two floating point values. The value returned is exact and does not depend on any rounding modes.

+

Error handling

This function is not subject to any of the error conditions specified in math_errhandling.

+

If the implementation supports IEEE floating-point arithmetic (IEC 60559),

+

Notes

This function is not required to be sensitive to the sign of zero, although some implementations additionally enforce that if one argument is +0 and the other is -0, then +0 is returned.

+

Example

#include <stdio.h>
+#include <math.h>
+ 
+int main(void)
+{
+    printf("fmax(2,1)    = %f\n", fmax(2,1));
+    printf("fmax(-Inf,0) = %f\n", fmax(-INFINITY,0));
+    printf("fmax(NaN,-1) = %f\n", fmax(NAN,-1));
+}

Output:

+
fmax(2,1)    = 2.000000
+fmax(-Inf,0) = 0.000000
+fmax(NaN,-1) = -1.000000
