IEEE_SUPPORT_DATATYPE([x])

IEEE_SUPPORT_DENORMAL([x])

IEEE_SUPPORT_DIVIDE([x])

IEEE_SUPPORT_FLAG(flag [, x])1

IEEE_SUPPORT_HALTING(flag)1

IEEE_SUPPORT_INF([x])

IEEE_SUPPORT_NAN([x])

IEEE_SUPPORT_ROUNDING(round_value [, x])2

IEEE_SUPPORT_SQRT([x])

1 "flag" must be a valid value

2 "round_value" must be a valid value
