| 28 | +* |
| 29 | +* - This function expects that the callback `info` argument provides access to the following JavaScript arguments: |
| 30 | +* |
| 31 | +* - `x`: input value. |
| 32 | +* - `y`: input value. |
| 33 | +* - `z`: input value. |
| 34 | +* - `w`: input value. |
| 35 | +* |
| 36 | +* @param env environment under which the function is invoked |
| 37 | +* @param info callback data |
| 38 | +* @param fcn quaternary function |
| 39 | +* @return function return value as a Node-API double-precision floating-point number |
