@stdlib/math-base-special-asindf v0.1.0

asindf

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

Installation

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

Usage

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

asindf( x )

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

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

var v = asindf( 0.0 );
// returns 0.0

v = asindf( 0.5 );
// returns ~30.0

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

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

v = asindf( NaN );
// returns NaN

The domain of x is restricted to [-1,1]. If |x| > 1, the function returns NaN.

var v = asindf( -3.14 );
// returns NaN

Examples

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

var x = linspace( -1.0, 1.0, 100 );

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

C APIs

Usage

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

stdlib_base_asindf( x )

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

float out = stdlib_base_asindf( 0.0f );
// returns 0.0f

out = stdlib_base_asindf( 0.5f );
// returns ~30.0f

The function accepts the following arguments:

• x: [in] float input value.

float stdlib_base_asindf( const float x );

Examples

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

int main( void ) {
    const float x[] = { 1.0f, 0.45f, -0.89f, 0.33f, -0.78f, -0.22f, 0.66f, 0.11f, -0.55f, 0.0f };
    
    float v;
    int i;
    for ( i = 0; i < 10; i++ ) {
        v = stdlib_base_asindf( x[ i ] );
        printf( "asind(%f) = %f\n", x[ i ], v );
    }
}
