Calculating the length of the hypotenuse using the standard formula `c = sqrt(a**2 + b**2)` may lead to overflow if the two other sides are both very large. Even though `c` will not be much bigger than `max(a, b)`, either `a**2` or `b**2` (or both) could be. Thus, the calculation could overflow, even though the result is well within representable range. It is recommended to use the built-in function `hypot(a,b)` from the `math` library.
