CHEAT SHEET: ROUNDING FUNCTIONS
Summary of ROUNDING Functions
Function & Description
Syntax & Example
ROUND
=ROUND(number, decimal places)
Rounds a number (up or down) to a
specified number of decimal places.
=ROUND(A1, 2) rounds the value in cell A1 to 2 decimal places
ROUNDUP
=ROUNDUP(number, decimal places)
Rounds a number UP to a specified
number of decimal places.
=ROUNDUP(A1, 2) rounds the value in cell A1 UP to 2 decimal places
ROUNDDOWN
=ROUND(number, decimal places)
Round a number DOWN to a
specified number of decimal places.
=ROUND (A1, 2) rounds the value in cell A1 DOWN to 2 decimal places
=ROUND(1234.567, 1) rounds to 1234.6 (1 decimal place)
=ROUNDUP(1234,1, 0) rounds UP to 1235 (0 decimal places)
=ROUND(1234.99999, 2) rounds to 1234.99 (2 decimal places)
For these first 3 functions, the number (first parameter) may be a number or a cell reference containing a
number.
The decimal places parameter may be set to

-1 to round to the nearest 10.

-2 it rounds to the nearest 100.

-3 it rounds to the nearest 1000 etc.
i.e. factors of 10
Function & Description
Syntax & Example
MROUND
=MROUND(number, multiple)
Round a number (up or down) to the =MROUND(A1, 5) rounds the value in A1 to the closest multiple of 5
nearest multiple.
=MROUND(123.456, 5) rounds to 125
CEILING
=CEILING (number, multiple)
Round a number up to a multiple.
=CEILING(A1, 5) rounds the value in A1 UP to the closest multiple of 5
=CEILING(123.456, 5) rounds to 125.
FLOOR
=FLOOR (number, multiple)
Round a number down to a multiple. =FLOOR(A1, 5) rounds the value in A1 DOWN to the closest multiple of 5
=FLOOR(123.456, 5) rounds to 120.

TRUNC
=TRUNC (number, decimal places)
Truncates a number to a specified
number of decimal places.
=TRUNC(A1, 2) discards the 3rd decimal place onwards
ABS
=ABS (number or cell reference)
Makes a number absolute – in
layman’s terms, this means that the
sign is removed from the number.
=ABS(5) gives 5
INT
=INT (number r cell reference)
Returns the whole part of a number,
discarding any decimal places.
=INT(123.456) gives 123
=TRUNC(123.456, 0) gives 123 (truncates the number at 0 decimal places)
=ABS(-5) gives 5
=INT(-123.456) gives -123
