     26 
     27 ## Usage
     28 
     29 ```javascript
     30 var xlog1py = require( '@stdlib/math/base/special/xlog1py' );
     31 ```

     33 #### xlog1py( x, y )
     34 
     35 Computes `x * ln(y+1)` so that the result is `0` if `x = 0`.
     36 
     37 ```javascript
     38 var out = xlog1py( 3.0, 2.0 );
     39 // returns ~3.296
     40 
     41 out = xlog1py( 1.5, 5.9 );
     42 // returns ~2.897
     43 
     44 out = xlog1py( 0.9, 1.0 );
     45 // returns ~0.624
     46 
     47 out = xlog1py( 1.0, 0.0 );
     48 // returns 0.0
     49 
     50 out = xlog1py( 0.0, -2.0 );
     51 // returns 0.0
     52 
     53 out = xlog1py( 1.5, NaN );
     54 // returns NaN
     55 
     56 out = xlog1py( 0.0, NaN );
     57 // returns NaN
     58 
     59 out = xlog1py( NaN, 2.3 );
     60 // returns NaN
