WorkingPrecision

Usage

• WorkingPrecision is an option for various numerical operations which specifies how many digits of precision should be maintained in internal computations.

Notes

• 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.

• See Section 3.9.3.
