Comment(by igloo):
Replying to [comment:41 igloo]:
? but the second and third should break (I'm not sure what they should
return. Whichever of Infinity, -Infinity, NaN and 0.0 best fits the
implementation, I guess).
Or perhaps if the exponent is `> FLT_MAX_EXP`, `< FLT_MIN_EXP`, `>
DBL_MAX_EXP` or `< DBL_MIN_EXP` then read should fail?
