About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

acscf

NPM version Build Status Coverage Status

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 );
    }
}
