# Maximum Natural Logarithm > [Natural logarithm][natural-logarithm] of the maximum [double-precision floating-point number][ieee754].

## Usage ```javascript var FLOAT64_MAX_LN = require( '@stdlib/constants/float64/max-ln' ); ``` #### FLOAT64_MAX_LN [Natural logarithm][natural-logarithm] of the maximum [double-precision floating-point number][ieee754]. ```javascript var bool = ( FLOAT64_MAX_LN === 709.782712893384 ); // returns true ```

## Examples ```javascript var FLOAT64_MAX_LN = require( '@stdlib/constants/float64/max-ln' ); console.log( FLOAT64_MAX_LN ); // => 709.782712893384 ```
