Zeros that do not affect the value

Today in mathematics we looked at zeros in numbers that do not affect their value.
When writing decimals one or more zeros can be added to the right of the decimal point, after the last digit, without affecting the value of the number.
For example:
4.2 = 4.20 = 4.200
2.5 = 2.50 = 2.500

Can you think of any other examples?
