There is a comment in ccoshf()

 	 /* x < 88.7: expf(|x|) won't overflow */

where is correct

The equivalent in ccosh() which says:

 	/* x < 710: exp(|x|) won't overflow */

This is far less concise than the earlier case.  More strictly

 	 /* x < 709.78: exp(|x|) won't overflow */

Am I being overly pedantic?

Thanks - Damian
