Prevent math errors by carefully bounds-checking before calling functions. In particular, the following domain errors should be prevented by prior bounds-checking:
| Code Block |
|---|
Function Bounds-checking |
...
acos |
...
(x), |
...
asin(x) -1 <= x && x <= 1 |
...
atan2 x != 0 || y != 0 log, log10 x >= 0 pow(x, y) x != 0 || y >= 0 |
...
sqrt(x) x >= 0
|
The calling function should take alternative action if these bounds are violated.
