How to increase the floating point precision of a number by using BigDecimals in java?

Question

Let's assume I have a string number such as 1000.0 and I want to create BigDecimal out of it in the following format: 1000.00

edit: And also if the string number already has a floating precision of two decimals, don't touch it.

How can I do this by using BigDecimals?.

Formatting and precision are different things. In math, `1000.0` and `1000.00` are identical. You might wanna have a look at [this post](https://stackoverflow.com/q/2538787) instead. — Siguza, Sep 18 '18 at 21:12

Use setScale(...), something like that:

BigDecimal result = new BigDecimal("1000.0");
result.setScale(2, RoundingMode.HALF_UP);
