WebUnlike NaNs, this invalid number can't be copied as > a `long double`. x87 loads it successfully using the `FLD` instruction, but > generates an #IA (invalid operand) exception if `FST` is used to store it > into RAM, which isn't the case for a SNaN or QNaN. It seems to be regarded as a NaN, not as a trap representation. WebJul 6, 2024 · For example, floating-point objects might be initialized to sNaN. Then, if the program fails to one of them a value before using it, an exception will occur when the program uses the sNaN in an arithmetic operation. A program will not produce an sNaN inadvertently; no normal operations produce sNaNs.
