More About »
WorkingPrecision
WorkingPrecision
is an option for various numerical operations which specifies how many digits of precision should be maintained in internal computations.
MORE INFORMATION
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.
