The Shorter Expressions bit is already in the docs.
Also, it might be worth adding a handy hint to the Rounding... bit: you can round a number by adding 0.5 to the number before truncating.
e.g.
2.9 + 0.5 = 3.4 (rounded off to 3)
3.1 + 0.5 = 3.6 (rounded off to 3)
3.5 + 0.5 = 4.0 (rounded off to 4)
etc.
