# Precision
> Effective number of bits in the [significand][significand] of a [single-precision floating-point number][ieee754].
## Usage
```javascript
var FLOAT32_PRECISION = require( '@stdlib/constants/float32/precision' );
```
#### FLOAT32_PRECISION
Effective number of bits in the [significand][significand] of a [single-precision floating-point number][ieee754].
```javascript
var bool = ( FLOAT32_PRECISION === 24 ); // including implicit bit
// returns true
```
## Examples
```javascript
var FLOAT32_PRECISION = require( '@stdlib/constants/float32/precision' );
console.log( FLOAT32_PRECISION );
// => 24
