Sri,

Thanks,

Subject: Regarding ranges for trignometric functions
Hi,
The LRM ranges for some of the math/trig functions are different from the std.
For pow(),
LRM says,
if x >= 0 all y,
if x < 0, int(y)
However, if x = 0, it should be y >= 0.
For sinh(x), it should probably be |x| < 80 instead of x < 80,
For cosh(x), it shoud probably be |x| < 80, instead of x < 80.
for atanh(x), -1 < x < 1, instead of -1 <= x <= 1
cheers,
Sri
