- Use precision instead of scale
- The default maximum precision is 20 digits
- The default rounding mode is HALF_UP
- The constructor takes only $num arguments
- The method can optionally specify any precision and any rounding mode when calculating
- Operators always use only default values in their calculations
Ah, that takes away the benefit of arbitrary precision...
Maybe I'm sleepy, forget about this.
