* Rounds each component of a single-precision complex floating-point number to the nearest multiple of `10^n` toward negative infinity.

* @private
* @param {Complex64} z - complex number
* @param {integer} n - integer power of 10
* @returns {Complex64} result
*
* @example
* var Complex64 = require( '@stdlib/complex/float32/ctor' );
*
* // Round components to the nearest ten:
* var v = cfloornf( new Complex64( -15.0, 15.0 ), 1 );
* // returns <Complex64>[ -20.0, 10.0 ]
*
* // If n = 0, `cfloornf` behaves like `cfloorf`:
* v = cfloornf( new Complex64( 9.99999, 0.1 ), 0 );
* // returns <Complex64>[ 9.0, 0.0 ]
*
* // Round components to the nearest hundred:
* v = cfloornf( new Complex64( 150.0, -150.0 ), 2 );
* // returns <Complex64>[ 100.0, -200.0 ]
*
* v = cfloornf( new Complex64( NaN, NaN ), 2 );
