# Arithmetic : Decimals

The decimal system can include fractions by using a period called the decimal point.
Every decimal fraction can be represented by a fraction, whose numerator is given by the digits to the right of the decimal point and whose denominator is given by 1 followed by zeros equal in number to the digits to the right of the decimal point. For example, 0.823 can be represented as 823/1000, where the numerator is 823 and the denominator is 1 followed by 3 zeros (since there are 3 digits to the right of the decimal point).
