 ROUTINES FOR ROUNDING IEEE-754 FLOATS TO SPECIFIED NUMBER OF DECIMAL FRACTIONS

  These routines round input values to fit as closely as possible to an
  output number with desired number of decimal fraction digits.

  Because, in general, numbers with decimal fractions cannot be exactly
  represented in IEEE-754 floating binary point variables, error limits
  are used to determine if the input numbers are intended to represent an
  exact decimal fraction rather than a nearby value.   Thus an error limit
  will be taken into account when deciding that a number input such as
  1.295, which internally is represented 1.29499 99999
