> I would like to get a number increased for 0.01:
Are you aware that in most programming languages (including ELisp) there
is no floating point number whose value is exactly 0.01?
If not, I suggest you either avoid floating point numbers, accept that
floating point numbers always are inexact, or read up on floating point
numbers (e.g. https://en.wikipedia.org/wiki/Floating-point_arithmetic)
