$MinPrecision

$MinPrecision
gives the minimum number of digits of precision to be allowed in arbitraryprecision numbers.

DetailsDetails

  • The default value of $MinPrecision is .
  • Positive values of $MinPrecision make the Wolfram Language pad arbitraryprecision numbers with zero digits to achieve the specified nominal precision. The zero digits are taken to be in base 2, and may not correspond to zeros in base 10.
  • $MaxPrecision=$MinPrecision=n makes the Wolfram Language do fixedprecision arithmetic.
  • $MinPrecision is measured in decimal digits, and need not be an integer.
