%description
Package inf (type inf.Dec) implements "infinite-precision" decimal arithmetic.
"Infinite precision" describes two characteristics: practically unlimited
precision for decimal number representation and no support for calculating with
any specific fixed precision. (Although there is no practical limit on
precision, inf.Dec can only represent finite decimals.)

This package is currently in experimental stage and the API may change.
