BUILT-IN MATHEMATICA SYMBOL

$MaxPrecision

$MaxPrecision
gives the maximum number of digits of precision to be allowed in arbitrary-precision numbers.

Details Details

The default value of $MaxPrecision is Infinity.
$MaxPrecision=Infinity uses the maximum value possible on a particular computer system, given roughly by Log[10, $MaxNumber].
$MaxPrecision is measured in decimal digits, and need not be an integer.

Limit a calculation to use at most 100 digits of precision:

Out[1]=

Do a computation with fixed 24 digit precision:

Out[1]=
