About stdlib...
We 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!
Compute the inverse half-value versed cosine.
The inverse half-value versed cosine is defined as
npm install @stdlib/math-base-special-ahavercos
Alternatively,
- To load the package in a website via a
script
tag without installation and bundlers, use the ES Module available on theesm
branch. - If you are using Deno, visit the
deno
branch. - For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the
umd
branch.
The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.
var ahavercos = require( '@stdlib/math-base-special-ahavercos' );
Computes the inverse half-value versed cosine.
var v = ahavercos( 0.0 );
// returns ~3.1416
v = ahavercos( 1.0 );
// returns 0.0
v = ahavercos( 0.5 );
// returns ~1.5708
If x < 0
, x > 1
, or x
is NaN
, the function returns NaN
.
var v = ahavercos( 1.5 );
// returns NaN
v = ahavercos( -3.14 );
// returns NaN
v = ahavercos( NaN );
// returns NaN
var linspace = require( '@stdlib/array-base-linspace' );
var ahavercos = require( '@stdlib/math-base-special-ahavercos' );
var x = linspace( 0.0, 1.0, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( ahavercos( x[ i ] ) );
}
