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!

Float32

NPM version Build Status Coverage Status

Base utilities for single-precision floating-point numbers.

Usage

To use in Observable,

ns = require( 'https://cdn.jsdelivr.net/gh/stdlib-js/number-float32-base@umd/browser.js' )

To vendor stdlib functionality and avoid installing dependency trees for Node.js, you can use the UMD server build:

var ns = require( 'path/to/vendor/umd/number-float32-base/index.js' )

To include the bundle in a webpage,

<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/stdlib-js/number-float32-base@umd/browser.js"></script>

If no recognized module system is present, access bundle contents via the global scope:

<script type="text/javascript">
(function () {
    window.ns;
})();
</script>

ns

Base utilities for single-precision floating-point numbers.

var o = ns;
// returns {...}
  • assert: base single-precision floating-point number assert functions.
  • exponentf( x ): return an integer corresponding to the unbiased exponent of a single-precision floating-point number.
  • fromBinaryStringf( bstr ): create a single-precision floating-point number from an IEEE 754 literal bit representation.
  • fromWordf( word ): create a single-precision floating-point number from an unsigned integer corresponding to an IEEE 754 binary representation.
  • normalizef(): return a normal number y and exponent exp satisfying x = y * 2^exp.
  • signbitf( x ): return a boolean indicating if the sign bit for a single-precision floating-point number is on (true) or off (false).
  • significandf( x ): return an integer corresponding to the significand of a single-precision floating-point number.
  • toBinaryStringf( x ): return a string giving the literal bit representation of a single-precision floating-point number.
  • float32ToInt32( x ): convert a single-precision floating-point number to a signed 32-bit integer.
  • float32ToUint32( x ): convert a single-precision floating-point number to an unsigned 32-bit integer.
  • toWordf( x ): return an unsigned 32-bit integer corresponding to the IEEE 754 binary representation of a single-precision floating-point number.
