# Bias > The bias of a [single-precision floating-point number's][ieee754] exponent.
## Usage ```javascript var FLOAT32_EXPONENT_BIAS = require( '@stdlib/constants/float32/exponent-bias' ); ``` #### FLOAT32_EXPONENT_BIAS The bias of a [single-precision floating-point number's][ieee754] exponent. ```javascript var bool = ( FLOAT32_EXPONENT_BIAS === 127 ); // returns true ```
## Examples ```javascript var FLOAT32_EXPONENT_BIAS = require( '@stdlib/constants/float32/exponent-bias' ); console.log( FLOAT32_EXPONENT_BIAS ); // => 127 ```
