[an error occurred while processing this directive] $MinPrecision

  • $MinPrecision gives the minimum number of digits of precision to be allowed in arbitrary-precision numbers.
  • The default value of $MinPrecision is 0.
  • 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.
  • See the Mathematica book: Section 3.1.5.
  • See also: SetPrecision, $MinNumber.
