Giving all possible values to four different variables

[quest_]

Beware floating point math. Many decimals cannot be represented exactly. Either check for approximate solutions, or do your math with integers and then divide by 10 later. Otherwise you will run into problems.

>>> 0.3 + 0.3 + 0.3 + 0.1 == 1.0
False

Workaround 1

>>> 3 + 3 + 3 + 1 == 10
True

Workaround 2

>>> 0.99 < 0.3 + 0.3 + 0.3 + 0.1 < 1.01
True

Workaround 3

>>> decimal.Decimal('0.3') + decimal.Decimal('0.3') + decimal.Decimal('0.3') + decimal.Decimal('0.1') == decimal.Decimal('1.0')
True

Many thanks, I did not notice that before!!!
