That's what I'm now using (I changed from using the original Math library a while back). JavaScript does have some interesting differences from the C implementation though (eg
NaNandInfinityhandling), so I'd have to be careful to only use it in the right circumstances - and also careful that it wasn't one of the functions that usesmallocfor no good reason - it's not as easy as a simple swap.
