    sinpi

    NPM version Build Status Coverage Status dependencies

    Compute the sine of a number times π.

    Installation

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

    Usage

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

    sinpi( x )

    Computes sin(πx) more accurately than sin(pi*x), especially for large x.

    var y = sinpi( 0.0 );
    // returns 0.0
    
    y = sinpi( 0.5 );
    // returns 1.0
    
    y = sinpi( 0.9 );
    // returns ~0.309
    
    y = sinpi( NaN );
    // returns NaN

    Examples

    var linspace = require( '@stdlib/array-linspace' );
    var sinpi = require( '@stdlib/math-base-special-sinpi' );
    
    var x = linspace( -100.0, 100.0, 100 );
    var i;
    
    for ( i = 0; i < x.length; i++ ) {
        console.log( sinpi( x[ i ] ) );
    }
