floorf

Round a single-precision floating-point numeric value toward negative infinity.

Usage

var floorf = require( '@stdlib/math/base/special/floorf' );

floorf( x )

Rounds a single-precision floating-point numeric value toward negative infinity.

var v = floorf( -4.2 );
// returns -5.0

v = floorf( 9.99999 );
// returns 9.0

v = floorf( 0.0 );
// returns 0.0

v = floorf( NaN );
// returns NaN

Examples

var randu = require( '@stdlib/random/base/randu' );
var floorf = require( '@stdlib/math/base/special/floorf' );

var x;
var i;

for ( i = 0; i < 100; i++ ) {
    x = (randu()*100.0) - 50.0;
    console.log( 'floorf(%d) = %d', x, floorf( x ) );
}

C APIs

Usage

#include "stdlib/math/base/special/floorf.h"

stdlib_base_floorf( x )

Rounds a single-precision floating-point number toward negative infinity.

float y = stdlib_base_floorf( 3.14f );
// returns 3.0

The function accepts the following arguments:

  • x: [in] float input value.
float stdlib_base_floor( const float x );

Examples

#include "stdlib/math/base/special/floorf.h"
#include <stdio.h>

int main() {
    float x[] = { 3.14f, -3.14f, 0.0f, 0.0f/0.0f };

    float y;
    int i;
    for ( i = 0; i < 4; i++ ) {
        y = stdlib_base_floorf( x[ i ] );
        printf( "floorf(%f) = %f\n", x[ i ], y );
    }
}
