Special Functions

Fast math special functions.

Installation

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

Usage

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

fmath

Namespace containing "fast" math special functions.

var fcns = fmath;
// returns {...}

• abs( x ): compute an absolute value.
• acosh( x ): compute the hyperbolic arccosine of a number.
• ampbm( x, y ): compute the hypotenuse using the alpha max plus beta min algorithm.
• asinh( x ): compute the hyperbolic arcsine of a number.
• atanh( x ): compute the hyperbolic arctangent of a number.
• hypot( x, y ): compute the hypotenuse.
• max( x, y ): return the maximum value.
• min( x, y ): return the minimum value.
• powint( base, exponent ): exponential function.
• log2Uint32( x ): compute an integer binary logarithm.
• sqrtUint32( x ): compute an integer square root.

Notes

• Implementations may violate strict IEEE semantics.
• Implementations may assume arguments and results are not NaN.
• Implementations may assume arguments are neither positive or negative infinity.
• Implementations may ignore the sign of zero.

Examples

var objectKeys = require( '@stdlib/utils-keys' );
var fmath = require( '@stdlib/math-base-special-fast' );

console.log( objectKeys( fmath ) );

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.
