This won't work the way you need it to. You need to compare against the bit sequence value for NaN. We do this in other benchmarks for float16.

Better would be to use the eventual number/float16/base/assert/is-nan utility here.

We can remove this, as this particular field was later found to be unnecessary at this level.

@Neerajpathak07 We should go ahead and add the binary macro for half-precision HH_H. Would you mind opening a PR for this?

We should go ahead and create a half-precision utility for this at number/float16/base/assert/is-negative-zero. Same thing for is-positive-zero and is-nan.

We'll eventually be moving math/base/assert/is-negative-zero to number/float64/base/assert/is-negative-zero, so we might as well go ahead and pre-emptively add the half-precision utilities.
