Function | Bounds-checking |
|---|---|
acos(x) | -1 <= x && x <= 1 |
atan2 | x != 0 || y != 0 |
log, log10 | x >= 0 |
pow(x, y) | x != 0 || y > 0 |
sqrt | x >= 0 |
The calling function should take alternative action if these bounds are violated.

pow(x,y)
Non-Compliant Example
The following code may produce a domain error if x is zero and y less than or equal to zero. A range error may also occur if x is zero and y is negative.
