Fix examples showing underscores in numbers

vadz · vadz · commit 71f25320246a · 2015-11-10T23:23:12.000+01:00
It was somewhat confusing to claim that `1_000_000` and `10_00_00` evaluate to the same number, make sure that all numbers have the same number of zeroes, even if they have different numbers of underscores.
