public final class BigUtils
extends Object

A utility class for BigDecimal math containing:

• BigDecimal versions of everything in Math that makes sense for BigDecimal and is not already implemented in BigDecimal itself.
• BigDecimal versions of everything in PrimitiveUtils.
• Useful constants
• A method that converts a Number to a BigDecimal
