math.exp returns inf instead of raising OverflowError

math.exp returns inf instead of raising OverflowError: a task in MiMo-V2.6-RL-harbor-code: MiMo-V2.6-RL Code (Harbor) (Harbor dataset). I'm porting some code from CPython to RustPython and noticed that math.exp doesn't behave the same way for large arguments.
