TO FLOAT64 // 
FUNCTION: toFloat64( high, low )
Creates a double-precision floating-point number from a higher order word (32-bit integer) and a lower order word (32-bit integer).

@param {Number} high - higher order word (unsigned 32-bit integer)
@param {Number} low - lower order word (unsigned 32-bit integer)
@returns {Number} floating-point number
function toFloat64( high, low ) {
	UINT32_VIEW[ HIGH ] = high;
	UINT32_VIEW[ LOW ] = low;
	return FLOAT64_VIEW[ 0 ];
