round

Definition: atom x2 = round(atom x1, atom inverted_precision=1)
Description: round x1 to the specified precision.
Comments: The precision is the inverse of what you might have expected, for example:
to round a number to the nearest 0.1, specify an inverted precision of 10,
to round a number to the nearest 1000, specify an inverted precision of 0.001.

This function may be applied to an atom or sq_round() to all elements of a sequence. The rules for sequence operations apply.
Example:
r = round(1.4)          -- r is 1
r = round(1.6)          -- r is 2
r = round(8.136,100)    -- r is 8.14
Implementation: See builtins\pmaths.e (an autoinclude) for details of the actual implementation.
