# How do you round BigDecimal to zero decimal places?

## How do you round BigDecimal to zero decimal places?

You can use setScale() to reduce the number of fractional digits to zero. Assuming value holds the value to be rounded: BigDecimal scaled = value. setScale(0, RoundingMode.

### What is precision and scale in BigDecimal?

By Definition, precision indicates the length of arbitrary precision integer whereas scale means the number of digits to the right of the decimal point. For example if we have a number “100.25” then precision is 5 because we need five digits to write down this number and scale is 2.

**What is rounding mode in BigDecimal Java?**

Description. The java. math. BigDecimal. setScale(int newScale, RoundingMode roundingMode) returns a BigDecimal whose scale is the specified value, and whose unscaled value is determined by multiplying or dividing this BigDecimal’s unscaled value by the appropriate power of ten to maintain its overall value.

**What is the default value for BigDecimal in Java?**

If you are using type BigDecimal, then its default value is null (it is object, not primitive type), so you get [1] automatically.

## What is BigDecimal scale Java?

A BigDecimal consists of an arbitrary precision integer unscaled value and a 32-bit integer scale. If zero or positive, the scale is the number of digits to the right of the decimal point. If negative, the unscaled value of the number is multiplied by ten to the power of the negation of the scale.

### How do I restrict decimal places in Java?

Using the format() method “%. 2f” denotes 2 decimal places, “%. 3f” denotes 3 decimal places, and so on. Hence in the format argument, we can mention the limit of the decimal places.

**What is the scale of a BigDecimal?**

**What is BigDecimal set scale?**

## How do you round a BigDecimal value?

math. BigDecimal. round(MathContext m) is an inbuilt method in Java that returns a BigDecimal value rounded according to the MathContext settings. If the precision setting is 0 then no rounding takes place.

### Can BigDecimal have null value?

You either never allow null values in database, application or view and initialize everything with new BigDecimal(0) or perform null checks on every usage for nullable values.

**How do I remove trailing zeros from BigDecimal?**

stripTrailingZeros() is an inbuilt method in Java that returns a BigDecimal which is numerically equal to this one but with any trailing zeros removed from the representation. So basically the function trims off the trailing zero from the BigDecimal value.
