Usage:
[number] y ← round( [scalar]x [, [number]nbdecs] )

Returns x rounded to nbdecs digits after the decimal place. nbdecs is set to 0 if not specified.

Examples:
round(10.1234) - yields 10
round(10.1234, 2) - yields 10.12
round(pctin(Q1,1),2) - Rounds after computing percent. Remember a percentage is between 0 and 1, so you'll probably want nbdecs >= 2.
round(pctin(round(z1),null,5) - Rounds before computing percent.
