public final class BigFunction
extends FunctionSet<java.math.BigDecimal>
```
Only the reference type parameter (BigDecimal) methods are actually implemented. The methods with the primitive parameters (double) should create a BigDecimal and then delegate to the primitive methods (and do nothing else). If possible the implementations should be pure BigDecimal arithmatic without rounding. If rounding is necessary MathContext.DECIMAL128 should be used. If BigDecimal arithmatic is not possible at all the implementation should delegate to PrimitiveFunction.
