Timo Rothenpieler	cb8ad005bb	avutil/half2float: adjust conversion of NaN ... IEEE-754 differentiates two different kind of NaNs. Quiet and Signaling ones. They are differentiated by the MSB of the mantissa. For whatever reason, actual hardware conversion of half to single always sets the signaling bit to 1 if the mantissa is != 0, and to 0 if it's 0. So our code has to follow suite or fate-testing hardware float16 will be impossible.	2022-08-19 22:09:36 +02:00
Mark Reid	8d19b3c4a5	avcodec/exr: preserve half-float NaN bits and add fate test ... Handles NaNs more like the official implementation handles them, preserving the original bits.	2020-12-09 12:31:09 +01:00
