137.5 ns Output value: FFC0 0000h
Exception handling ports: nan asserts
The inverse square root of a negative value produces a NaN.
20 ns data[] value: 0000 0004h
The is a denormal value.
147.5 ns Output value: 7F80 0000h
Denormal numbers are forced-zero values, therefore the inverse square root of zero
results in infinity.
Exception handling ports: nan deasserts, division_by_zero asserts
50 ns data[] value: 7F80 0000h
This is an infinity value.
177.5 ns Output value: 0000 0000h
The inverse square root of an infinity value produces a zero.
Exception handling ports: zero asserts
