Float32

Base utilities for single-precision floating-point numbers.

Installation

npm install @stdlib/number-float32-base

Usage

var ns = require( '@stdlib/number-float32-base' );

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.

Examples

var objectKeys = require( '@stdlib/utils-keys' );
var ns = require( '@stdlib/number-float32-base' );

console.log( objectKeys( ns ) );

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.
