So in the Numeric Operations section, I think integer division should be covered as it may be a bit confusing that 4999/1000 gives 4 and not 5 to people coming from languages like javascript where numbers aren't separated into ints and floats.

Something like -

With integers, division is automatically floored so doing 4999/1000 will give 4 and not 5.
