acscf

Compute the arccosecant of a single-precision floating-point number.

Installation

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

Usage

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

acscf( x )

Computes the arccosecant of a single-precision floating-point number.

var v = acscf( 1.0 );
// returns ~1.57

v = acscf( 3.141592653589793 );
// returns ~0.32

v = acscf( -3.141592653589793 );
// returns ~-0.32

If |x| < 1, the function returns NaN.

var v = acscf( 0.5 );
// returns NaN

Examples

var linspace = require( '@stdlib/array-base-linspace' );
var acscf = require( '@stdlib/math-base-special-acscf' );

var x = linspace( 1.1, 5.1, 100 );

var i;
for ( i = 0; i < x.length; i++ ) {
    console.log( acscf( x[ i ] ) );
}

C APIs

Usage

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

stdlib_base_acscf( x )

Computes the arccosecant of a single-precision floating-point number.

float out = stdlib_base_acscf( 1.0f );
// returns ~1.57f

The function accepts the following arguments:

• x: [in] float input value.

float stdlib_base_acscf( const float x );

Examples

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

int main( void ) {
    const float x[] = { -5.0f, -3.89f, -2.78f, -1.67f, -0.56f, 0.56f, 1.67f, 2.78f, 3.89f, 5.0f };
    
    float v;
    int i;
    for ( i = 0; i < 10; i++ ) {
        v = stdlib_base_acscf( x[ i ] );
        printf( "acsc(%f) = %f\n", x[ i ], v );
    }
}
