acscdf

Compute the arccosecant (in degrees) of a single-precision floating-point number.

Installation

npm install @stdlib/math-base-special-acscdf

Usage

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

acscdf( x )

Computes the arccosecant (in degrees) of a single-precision floating-point number.

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

var v = acscdf( Infinity );
// returns 0.0

v = acscdf( 2.0 * sqrtf( 3.0 ) / 3.0 );
// returns ~60.0

v = acscdf( sqrtf( 2.0 ) );
// returns ~45.0

v = acscdf( 2.0 );
// returns ~30.0

v = acscdf( 1.0 );
// returns 90.0

v = acscdf( NaN );
// returns NaN

Examples

var uniform = require( '@stdlib/random-array-uniform' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var acscdf = require( '@stdlib/math-base-special-acscdf' );

var x = uniform( 100, 1.1, 5.1, {
    'dtype': 'float32'
});

logEachMap( 'acscdf(%0.4f) = %0.4f', x, acscdf );

C APIs

Usage

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

stdlib_base_acscdf( x )

Computes the arccosecant (in degrees) of a single-precision floating-point number.

float out = stdlib_base_acscdf( 1.0f );
// returns 90.0f

out = stdlib_base_acscdf( 2.0f );
// returns ~30.0f

The function accepts the following arguments:

• x: [in] float input value.

float stdlib_base_acscdf( const float x );

Examples

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

int main( void ) {
    const float x[] = { 1.1f, 1.55f, 1.99f, 2.44f, 2.88f, 3.32f, 3.77f, 4.21f, 4.66f, 5.1f };

    float v;
    int i;
    for ( i = 0; i < 10; i++ ) {
        v = stdlib_base_acscdf( x[ i ] );
        printf( "acscd(%f) = %f\n", x[ i ], v );
    }
}
