abstract = "Mathematica provides both traditional machine-level
floating point numbers and software-implemented
variable-precision floating-point numbers. There are
two different notions of precision: an estimate of the
maximum possible relative error, which is propagated
through arithmetic operations based on the precision of
the operands; and the number of digits used to
represent the significand (mantissa). Mathematica links
the first notion to the second, throwing away digits
that it cannot prove are significant. In iterative
calculations the precision can ratchet down a little
each iteration, until there is nothing left.",
