x: aexp
n: iexp

The function ROUND(x) returns x rounded to the nearest whole number. The
variant ROUND(x,n) rounds the expression x to n decimal places. If n is zero,
the effect is the same as for ROUND(x). If n is negative, the rounding is done
before the decimal point, so ROUND(155,-1) results in the number 160,
(Note: CINT() also rounds with an Integer result.)

Examples:

    y=ROUND(-1.2)
    PRINT y,ROUND(1.7)

--> Displays -1 and 2 on the screen.

    FOR i%=-5 TO 5
      PRINT i%,ROUND(PI*100,i%)
    NEXT i%

--> Displays the loop variable and the associated formatted expression on the
    screen: PI is multiplied by 100 and then displayed rounded to i% decimal
    places. Where i% is negative, the rounding is done to the left of the
    decimal point.
