ROUND() returns a rounded whole number from a numeric expression or field value. Use ROUND() whenever you want to round an expression to the nearest whole number.
ROUND(N)
ROUND() returns a number equal to the numeric expression or field value N rounded to the nearest integer. This function rounds 0.5 upwards (for example, away from zero).
This function is exactly the same as:
DECIMAL(N,0)
ROUND(7.2) = 7
ROUND(7.5) = 8
ROUND(-7.5) = -8
To create a field that is equal to the balance rounded to the nearest dollar value, specify:
ROUND(Balance)
