# Arithmetic with double

You may find that

System.out.println( 1.33 - 1.3 ); // output : 0.030000000000000027

The unexpected result is coming from the fact that internal floating-point number representation is not well suited for that kind of operation. The easiest way to solve this limitation is to the BigDecimal class :

import java.math.BigDecimal; ... System.out.println (new BigDecimal("1.33").subtract(new BigDecimal("1.3")));
