/**
* Rounds a double-precision floating-point number to the nearest multiple of `10^n` toward negative infinity.
*
* ## Notes
*
* -   When operating on floating-point numbers in bases other than `2`, rounding to specified digits can be inexact.
*
* @param x - input value
* @param n - integer power of 10
* @returns rounded value
*
* @example
* // Round a value to 4 decimal places:
* var v = floorn( 3.141592653589793, -4 );
* // returns 3.1415
*
* @example
* // If n = 0, `floorn` behaves like `floor`:
* var v = floorn( 3.141592653589793, 0 );
* // returns 3.0
*
* @example
* // Round a value to the nearest thousand:
* var v = floorn( 12368.0, 3 );
* // returns 12000.0
