/**
* Evaluates the signum function of a single-precision floating-point complex number stored in a real-valued strided array view and assigns results to a provided strided output array.
*
* @param {Float32Array} z - complex number view
* @param {integer} strideZ - stride length for `z`
* @param {NonNegativeInteger} offsetZ - starting index for `z`
* @param {Collection} out - output array
* @param {integer} strideOut - stride length for `out`
* @param {NonNegativeInteger} offsetOut - starting index for `out`
* @returns {Collection} output array
*
* @example
* var Float32Array = require( '@stdlib/array/float32' );
*
* var z = new Float32Array( [ -4.2, 5.5 ] );
*
* var out = strided( z, 1, 0, new Float32Array( 2 ), 1, 0 );
* // returns <Float32Array>[ ~-0.607, ~0.795 ]
