In JEP 8 - 7.9 would give 0.09999999999999964 rather than 0.1.Is there any API in java which solves a mathematical expression with out giving such problem

If precision is that import, you can use java.math.BigDecimal. But be aware that calculations will be slower than using simple type arithmetics.
