Why? This is no different than if they set any of the other
four billion possible values.
What do you mean?
operation on float.nan gives you a float.nan so why does the
shortcut evaluate to true and not false wouldnt that make more
sense?
NaN in IEEE 754 floating-point numbers (the floating-point number
system most languages and processors use) is defined as a number
with all exponent bits set and a non-zero mantissa. The mantissa
value is the "NaN payload", and can be any value.
`is` does a binary comparison on floating-point numbers, so NaNs
with different payloads will not be considered equal, as you have
found out with `float.init !is float.nan`.
