Representation of decimal numbers

A decimal number is composed of two parts separated by a comma: the integer part is the number to the left of the comma and the fractional (or decimal) part is the number to the right of the comma.

The number 1.24 can be broken down as follows:

1.24 = 1 + 0.24

1 is the integer part and 0.24 is the decimal part (or fractional part, as it can be written as 24/100 - "twenty-four hundredths").

The decimal part is always less than 1 because it is a fraction of the unit.
