$MinPrecision

$MinPrecision
gives the minimum number of digits of precision to be allowed in arbitrary-precision numbers.
  • Positive values of $MinPrecision make Mathematica pad arbitrary-precision 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 Mathematica do fixed-precision arithmetic.
  • $MinPrecision is measured in decimal digits, and need not be an integer.
