Mask for the significand of a single-precision floating-point number.
npm install @stdlib/constants-float32-significand-maskWe 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!

> Mask for the significand of a [single-precision floating-point number][ieee754].
``bash`
npm install @stdlib/constants-float32-significand-mask
`javascript`
var FLOAT32_SIGNIFICAND_MASK = require( '@stdlib/constants-float32-significand-mask' );
#### FLOAT32_SIGNIFICAND_MASK
Mask for the significand of a [single-precision floating-point number][ieee754].
`javascript`
// 0x007fffff = 8388607 => 0 00000000 11111111111111111111111
var bool = ( FLOAT32_SIGNIFICAND_MASK === 0x007fffff );
// returns true
`javascript
var toWord = require( '@stdlib/number-float32-base-to-word' );
var FLOAT32_SIGNIFICAND_MASK = require( '@stdlib/constants-float32-significand-mask' );
var x = 11.5;
var w = toWord( x ); // 0 10000010 01110000000000000000000
// returns 1094189056
// Mask off all bits except for the significand bits:
var out = w & FLOAT32_SIGNIFICAND_MASK; // 0 00000000 01110000000000000000000
// returns 3670016
// Mask on the significand bits and leave other bits unchanged:
out = w | FLOAT32_SIGNIFICAND_MASK; // 0 10000010 11111111111111111111111
// returns 1098907647
