CIGAL Reference Manual, Chapter 3 (Functions): round
usage: result = round(x)
ROUND converts real numbers to integer numbers by rounding each value to the nearest integral value. Values exactly halfway between two integers are rounded up. If the input X is a variable with more than one value, ROUND will generate an output variable with the same number of values.
