## Usage
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var FLOAT64_GAMMA_LANCZOS_G = require( '@stdlib/constants/float64/gamma-lanczos-g' );
|
||
|
|
```
|
||
|
|
|
||
|
|
#### FLOAT64_GAMMA_LANCZOS_G
|
||
|
|
|
||
|
|
Arbitrary constant `g` to be used in [Lanczos approximation][lanczos-approximation] functions.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var bool = ( FLOAT64_GAMMA_LANCZOS_G === 10.900511 );
|
||
|
|
// returns true
|
||
|
|
```
