IntegerUtil (MicroFlex - Integer 1.0.1 API)

java.lang.Object
- com.github.jessemull.microflexinteger.util.IntegerUtil

```
public class IntegerUtil
extends Object
```
This class safely converts (1) integer values to lists or arrays of another numeric type (2) a value from another numeric type to an integer. The utility supports conversion to and from all Java primitives as well as two immutable data types:

Primitives

Byte

Short

Int

Long

Float

Double

Immutables

BigInteger

BigDecimal

This class throws an arithmetic exception on overflow.
