## Installation ```bash npm install @stdlib/constants-float64-pinf ```

## Usage ```javascript var FLOAT64_PINF = require( '@stdlib/constants-float64-pinf' ); ``` #### FLOAT64_PINF [Double-precision floating-point][ieee754] positive infinity. ```javascript var bool = ( FLOAT64_PINF === Infinity ); // returns true ```

## Examples ```javascript var FLOAT64_PINF = require( '@stdlib/constants-float64-pinf' ); console.log( FLOAT64_PINF ); // => Infinity ```
