    Square Root of Epsilon

    NPM version Build Status Coverage Status dependencies

    Square root of half-precision floating-point epsilon.

    Installation

    npm install @stdlib/constants-float16-sqrt-eps

    Usage

    var FLOAT16_SQRT_EPSILON = require( '@stdlib/constants-float16-sqrt-eps' );

    FLOAT16_SQRT_EPSILON

    Square root of half-precision floating-point epsilon.

    var bool = ( FLOAT16_SQRT_EPSILON === 0.03125 );
    // returns true

    Examples

    var abs = require( '@stdlib/math-base-special-abs' );
    var maxabs = require( '@stdlib/math-base-special-maxabs' );
    var randu = require( '@stdlib/random-base-randu' );
    var FLOAT16_SQRT_EPSILON = require( '@stdlib/constants-float16-sqrt-eps' );
    
    var bool;
    var a;
    var b;
    var i;
    
    function isApprox( a, b ) {
        var delta;
        var tol;
    
        delta = abs( a - b );
        tol = FLOAT16_SQRT_EPSILON * maxabs( a, b );
    
        return ( delta <= tol );
    }
    
    for ( i = 0; i < 100; i++ ) {
        a = randu() * 10.0;
        b = a + (randu()*0.2) - 0.1;
        bool = isApprox( a, b );
        console.log( '%d %s approximately equal to %d', a, ( bool ) ? 'is' : 'is not', b );
    }
