roundeven, roundevenf, roundevenl

Defined in header <math.h> 
float       roundevenf( float arg );
-		 (1) (since C23) 
double      roundeven( double arg );
-		 (2) (since C23) 
long double roundevenl( long double arg );
-		 (3) (since C23)
Defined in header <tgmath.h> 
#define roundeven( arg )
-		 (4) (since C23)
-1-3) Computes the nearest integer value to arg (in floating-point format), rounding halfway cases to nearest even integer, regardless of the current rounding mode.
-4) Type-generic macro: If arg has type long double, roundevenl is called. Otherwise, if arg has integer type or the type double, roundeven is called. Otherwise, roundevenf is called, respectively.

Parameters

- -
arg - floating point value

Return value

If no errors occur, the nearest integer value to arg, rounding halfway cases to nearest even integer, is returned.

-

Error handling

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

-

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

-

Example

#include <math.h>
-#include <stdio.h>
-int main(void)
-{
-    printf("roundeven(+2.4) = %+.1f\n", roundeven(2.4));
-    printf("roundeven(-2.4) = %+.1f\n", roundeven(-2.4));
-    printf("roundeven(+2.5) = %+.1f\n", roundeven(2.5));
-    printf("roundeven(-2.5) = %+.1f\n", roundeven(-2.5));
-    printf("roundeven(+2.6) = %+.1f\n", roundeven(2.6));
-    printf("roundeven(-2.6) = %+.1f\n", roundeven(-2.6));
-    printf("roundeven(+3.5) = %+.1f\n", roundeven(3.5));
-    printf("roundeven(-3.5) = %+.1f\n", roundeven(-3.5));
-    printf("roundeven(-0.0) = %+.1f\n", roundeven(-0.0));
-    printf("roundeven(-Inf) = %+f\n",   roundeven(-INFINITY));
-}

Possible output:

-
roundeven(+2.4) = +2.0
-roundeven(-2.4) = -2.0
-roundeven(+2.5) = +2.0
-roundeven(-2.5) = -2.0
-roundeven(+2.6) = +3.0
-roundeven(-2.6) = -3.0
-roundeven(+3.5) = +4.0
-roundeven(-3.5) = -4.0
-roundeven(-0.0) = -0.0
-roundeven(-Inf) = -inf
