is an option for various numerical operations that specifies how many digits of precision should be maintained in internal computations.
- WorkingPrecision is an option for such functions as NIntegrate and FindRoot.
- Setting WorkingPrecision->n causes all internal computations to be done to at most n‐digit precision.
- Setting WorkingPrecision->MachinePrecision causes all internal computations to be done with machine numbers.
- Even if internal computations are done to n‐digit precision, the final results you get may have much lower precision.
