NumVal (kink API)

java.lang.Object
- org.kink_lang.kink.HostResultCore
- - org.kink_lang.kink.Val
  - - org.kink_lang.kink.NumVal

All Implemented Interfaces:

HostResult
```
public class NumVal
extends Val
```
A num val.
A num val consists of two integers: mantissa and scale. The num val represents an decimal number (mantissa * 10**(-scale)). Kink runtimes must support arbitrary range for mantissa as far as the memory is not exhausted, and at least the range [-32767, +32767] for scale.

In this implementation, a num val is backed by a Java BigDecimal. The mantissa is the “unscaled value” of BigDecimal, and the scale is the “scale” of BigDecimal.

- Method Detail
  - getBigDecimal
```
public BigDecimal getBigDecimal()
```
    Returns the big decimal number.
    
    Returns:
    
    the big decimal number.
  - getCustomVarMapping
```
public VarMapping getCustomVarMapping()
```
    Description copied from class: Val
    
    Returns the var mapping for a val class.
    Override this method to provide vars common to the val class. The content of the var mapping is preferred than the common ones.
    
    Overrides:

    Overrides:
    
    toString in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object arg)
