ASIN function broken

As at 121031, the ASIN function seems to be broken.

Applying it to a 1V pk sinusoidal signal results in periodic glitches at the peaks.

It is suspected that this is caused by rounding or other numerical errors.

It is likely that the ACOS function suffers the same problem, although this has not been investigated.

For examples of this behaviour, please see:
