`exp(89.0f)` is NaN
A comment in the header states:
exp(88.722839f) = inf ; 0x42b17218
This is indeed the result I'm seeing.
However, at least on my machine exp(89.0f) is NaN and not inf, and that's causing a problem in my use case.
I think the problem is that here, limit is the input value (x) rounded to an integer (such as 89), and it's compared to 0x42b00000 that is a very large integer (so basically we never go to the clamping code guarded by this if statement). I think it's quite clear that this is an apples-to-oranges comparison... I think I understand what the general intent here has been, but to me it seems that there's just a simple bug.
Thank you for the report. I will merge the patches, but I'm busy at work now, so please wait a moment.
I'm sorry for the long delay. The new version fixes this. However, it is not backward compatible with previous versions.
