isNaN property
latefinal
Return a Logic 1if this FloatingPoint is Not a Number (NaN)
by having its exponent field set to the NaN value (typically all
ones) and a non-zero mantissa.
Implementation
late final Logic isNaN = (supportsSignalingNaNs
? exponent.eq(valuePopulator().nan.exponent) & _fraction.or()
: exponent.eq(valuePopulator().nan.exponent) &
mantissa.eq(valuePopulator().nan.mantissa))
.named(_nameJoin('isNaN', name), naming: Naming.mergeable);
