RE: [Fwd: Change made to atan2()]

David,
FYI from Steven Sharp, it was already noticed and fixed for the next rev
the digital standard; P1800.

Hi, Ken pointed out to me that the atan2() function in the LRM differs
from the C (and other programming languages, matlab etc.) definition.

currently in the LRM (chap 4) we define atan2()
atan2(x,y) - arc tangent x / y

This is also the same as the definition in the Verilog 2005 standard
(which I guess we cut and pasted).

This function should be defined as:
atan2(y,x) - arc tangent y / x

Unless anyone strongly objects, I will go ahead and correct this
definition.

Cheers...
Dave
