It expands to a bitmask of those exceptions (FP_EX_* values) for which trapping (sending a signal) is enabled. This is only relevant for cases of exact underflow (where a signal is sent if trapping on underflow is enabled, but otherwise the underflow flag is not raised). Typically a masked version of the floating-point control register, shifted to move the trap-enabled bits into the positions of the exception-raised bits, is right. -- Joseph S.
