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!
Convert an angle from radians to degrees (single-precision).
import rad2degf from 'https://cdn.jsdelivr.net/gh/stdlib-js/math-base-special-rad2degf@esm/index.mjs';The previous example will load the latest bundled code from the esm branch. Alternatively, you may load a specific version by loading the file from one of the tagged bundles. For example,
import rad2degf from 'https://cdn.jsdelivr.net/gh/stdlib-js/math-base-special-rad2degf@v0.1.2-esm/index.mjs';Converts an angle from radians to degrees (single-precision).
var d = rad2degf( 3.141592653589793 / 2.0 );
// returns 90.0
d = rad2degf( -3.141592653589793 / 4.0 );
// returns -45.0
d = rad2degf( NaN );
// returns NaN-
Due to finite precision, canonical values may not be returned. For example,
var d = rad2degf( 3.141592653589793 / 6.0 ); // returns 30.000001907348633
