"An sNaN (signaling Not-a-Number) is a special floating-point value that is designed to trigger a hardware trap or exception when it is used in an arithmetic operation. This differs from a qNaN (quiet Not-a-Number), which propagates through calculations without causing an immediate exception. Handling sNaNs requires a more deliberate approach that involves enabling floating-point traps and writing a custom trap handler."

Just learned something. Thanks.
