Round to Even (ROUNDE)

The round-to-even method is used in engineering, finance, and computer science to reduce bias when you use rounded numbers to estimate sums and averages. The round-to-even method works like this:
  • If the difference between the number and the nearest integer is less than 0.5, round to the nearest integer. This familiar rule is used by many rounding methods.
  • If the difference between the number and the nearest integer is exactly 0.5, look at the integer part of the number. If the integer part is EVEN, round towards zero. If the integer part of the number is ODD, round away from zero. In either case, the rounded number is an even integer.
[function] --> [output]
ROUNDE(1.465,2) --> 1.46
ROUNDE(1.5) --> 2
ROUNDE(2.5) --> 2
ROUNDE("a",2) --> invalid

Exponential (EXP)

Power (POW)

Arithmetic operations

Besides the above described functions, basic arithmetic operations can be also used.

Plus (+)

  • Takes 2 arguments.
  • Both arguments have to be numbers or a variables.
input = 6
[function] --> [output]
4+2 --> 6
{input}+2 --> 8
3+{input} --> 9
x+x --> invalid

Minus (-)

  • Takes 1 or 2 arguments, yet the second argument always has to be there.
  • Both arguments have to be numbers or a variables.
input = 6
[function] --> [output]
4-2 --> 2
{input}-1 --> 5
9-{input1} --> 3
-1 --> -1
3- --> invalid
x-x --> invalid
For the minus operation to work correctly, it is necessary to use brackets to specify the desired order of the operations, e.g. write (1-1)-1 or (-3)*5 instead of merely 1 - 1 - 1 or -3*5, respectively.

Times (*)

input = 6
[function] --> [output]
4*2 --> 8
{input}*2 --> 12
5*(-2) --> -10
x*x --> invalid

Divided (/)

input = 6
[function] --> [output]
4/2 --> 2
18/{input} --> 3
30/(-6) --> -5
x/x --> invalid
You may use the above described basic operations in the usual way, writing more complex expressions with the use of brackets (), for example:
input = 3
[function] --> [output]
1+2+(-3) --> 0
1-(4+5+2*{input})/3 --> -4
(4+9)*(4+9) - (4*4 + 2*4*9 + 9*9) --> 0
It is also possible to use arithmetic operations together with other functions:
input = 6
[function] --> [output]
SUM(1,2,-3) --> 0
1-AVG(4,5,2*{input}) --> -4
POW(4+9,2) - (POW(4,2) + 2*4*9 + POW(9,2)) --> 0
