/**
* Tests whether two single-precision complex floating-point numbers are the same value.
*
* ## Notes
*
* - The function implements the [SameValue Algorithm][ecma-262-same-value-algorithm], as specified in ECMAScript 5.
* - In contrast to the strict equality operator `===`, `-0` and `+0` are distinguishable and `NaNs` are the same.
*
* [ecma-262-same-value-algorithm]: http://ecma-international.org/ecma-262/5.1/#sec-9.12
*
* @param {Complex64} z1 - first complex number
* @param {Complex64} z2 - second complex number
* @returns {boolean} result
*
* @example
* var Complex64 = require( '@stdlib/complex/float32/ctor' );
*
* var z1 = new Complex64( 5.0, 3.0 );
* var z2 = new Complex64( 5.0, 3.0 );
*
* var v = isSameValue( z1, z2 );
* // returns true
