Fast math special functions.
npm install @stdlib/math-base-special-fastWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

``bash`
npm install @stdlib/math-base-special-fast
`javascript`
var fmath = require( '@stdlib/math-base-special-fast' );
#### fmath
Namespace containing "fast" math special functions.
`javascript`
var fcns = fmath;
// returns {...}
- [abs( x )][@stdlib/math/base/special/fast/abs]: compute an absolute value.
- [absf( x )][@stdlib/math/base/special/fast/absf]: compute the absolute value of a single-precision floating-point number.
- [acosh( x )][@stdlib/math/base/special/fast/acosh]: compute the hyperbolic arccosine of a number.
- [ampbm( x, y )][@stdlib/math/base/special/fast/alpha-max-plus-beta-min]: compute the hypotenuse using the alpha max plus beta min algorithm.
- [asinh( x )][@stdlib/math/base/special/fast/asinh]: compute the hyperbolic arcsine of a number.
- [atanh( x )][@stdlib/math/base/special/fast/atanh]: compute the hyperbolic arctangent of a number.
- [hypot( x, y )][@stdlib/math/base/special/fast/hypot]: compute the hypotenuse.
- [max( x, y )][@stdlib/math/base/special/fast/max]: return the maximum value.
- [min( x, y )][@stdlib/math/base/special/fast/min]: return the minimum value.
- [powint( base, exponent )][@stdlib/math/base/special/fast/pow-int]: exponential function.
- [log2Uint32( x )][@stdlib/math/base/special/fast/uint32-log2]: compute an integer binary logarithm.
- [sqrtUint32( x )][@stdlib/math/base/special/fast/uint32-sqrt]: compute an integer square root.
- Implementations may violate strict IEEE semantics.
- Implementations may assume arguments and results are not NaN.infinity
- Implementations may assume arguments are neither positive or negative .
- Implementations may ignore the sign of zero.
