    deg2radf

    NPM version Build Status Coverage Status dependencies

    Convert an angle from degrees to radians (single-precision).

    Installation

    npm install @stdlib/math-base-special-deg2radf

    Usage

    var deg2radf = require( '@stdlib/math-base-special-deg2radf' );

    deg2radf( x )

    Converts an angle from degrees to radians (single-precision).

    var r = deg2radf( 90.0 );
    // returns ~1.571
    
    r = deg2radf( -45.0 );
    // returns ~-0.785
    
    r = deg2radf( NaN );
    // returns NaN

    Examples

    var randu = require( '@stdlib/random-base-randu' );
    var deg2radf = require( '@stdlib/math-base-special-deg2radf' );
    
    var d;
    var r;
    var i;
    
    for ( i = 0; i < 100; i++ ) {
        d = (randu()*720.0) - 360.0;
        r = deg2radf( d );
        console.log( 'degrees: %d => radians: %d', d, r );
    }

    C APIs

    Installation

    npm install @stdlib/math-base-special-deg2radf

    Usage

    #include "stdlib/math/base/special/deg2radf.h"

    stdlib_base_deg2radf( x )

    Converts an angle from degrees to radians (single-precision).

    float y = stdlib_base_deg2radf( 90.0f );
    // returns ~1.571f

    The function accepts the following arguments:

    • x: [in] float input value.
    float stdlib_base_deg2radf( const float x );

    Examples

    #include "stdlib/math/base/special/deg2radf.h"
    #include <stdio.h>
    
    int main() {
        float x[] = { 45.0f, 90.0f, 0.0f, 0.0f/0.0f };
    
        float y;
        int i;
        for ( i = 0; i < 4; i++ ) {
            y = stdlib_base_deg2radf( x[ i ] );
            printf( "deg2radf(%f) = %f\n", x[ i ], y );
        }
    }
