# FLOAT32_PINF > [Single-precision floating-point][ieee754] positive infinity.

## Usage ```javascript var FLOAT32_PINF = require( '@stdlib/constants/float32/pinf' ); ``` #### FLOAT32_PINF [Single-precision floating-point][ieee754] positive infinity. ```javascript // FLOAT32_PINF is implicitly promoted to a double-precision floating-point number... var bool = ( FLOAT32_PINF === Infinity ); // returns true ```

## Examples ```javascript var FLOAT32_PINF = require( '@stdlib/constants/float32/pinf' ); console.log( FLOAT32_PINF ); // => Infinity ```
