Arithmetic overflow can occur in the following scenarios:

  • Addition
  • Subtraction
  • Multiplication
  • Division
  • Increment
  • Decrement
  • Creating PSXFixed from a double or from_integer() where the input is outside the bounds of the fixed-point type

Currently, the behaviour of overflowing operations is unspecified. It should be specified, tested for, and documented, regardless of whether we decide to catch it or not.
