    Kernel Sine

    NPM version Build Status Coverage Status dependencies

    Compute the sine of a number on [-π/4, π/4].

    Installation

    npm install @stdlib/math-base-special-kernel-sin

    Usage

    var kernelSin = require( '@stdlib/math-base-special-kernel-sin' );

    kernelSin( x, y )

    Computes the sine of a number on [-π/4, π/4]. For increased accuracy, the number for which the sine should be evaluated can be supplied as a double-double number (i.e., a non-evaluated sum of two double-precision floating-point numbers x and y).

    var v = kernelSin( 0.0, 0.0 );
    // returns ~0.0
    
    v = kernelSin( 3.141592653589793/6.0, 0.0 );
    // returns ~0.5
    
    v = kernelSin( 0.619, 9.279e-18 );
    // returns ~0.58
    
    v = kernelSin( NaN, 0.0 );
    // returns NaN
    
    v = kernelSin( 3.0, NaN );
    // returns NaN
    
    v = kernelSin( NaN, NaN );
    // returns NaN

    Notes

    Examples

    var linspace = require( '@stdlib/array-linspace' );
    var PI = require( '@stdlib/constants-float64-pi' );
    var kernelSin = require( '@stdlib/math-base-special-kernel-sin' );
    
    var x = linspace( -PI/4.0, PI/4.0, 100 );
    var i;
    
    for ( i = 0; i < x.length; i++ ) {
        console.log( 'kernelSin(%d) = %d', x[ i ], kernelSin( x[ i ], 0.0 ) );
    }

    Notice

    This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
