The float (or double if optional double is supported) value given by data is first converted to a half value using the appropriate rounding mode. The half value is then written to address computed as ( p + offset ). The address computed as ( p + offset) must be 16-bit aligned. vstore_half uses the current rounding mode. lantern batmanWebOpenCL does not define what happens for the non-saturated conversions when floating-point operands are outside the range representable integers after rounding.
