$MinPrecision

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

The default value of $MinPrecision is -Infinity.

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 Section 3.1.5.
