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

Summation (SUM)

Sums up numerical values.

• Takes any number of arguments greater than 0.

• Each argument must be a number or a variable.

• Alternatively, SUM can take an array of numbers in any argument.

Input Example:

// variables input

input1 = 3
input2 = [1,2,3]

// [function] --> [output]

SUM(1,2)           --> 3
SUM(1,2,3)         --> 6
SUM({input1},6)    --> 9
SUM({input2})      --> 6
SUM({input2},4)    --> 10
SUM("1")           --> 1
SUM(1)             --> 1

SUM("a","b")     --> invalid

Times (*)

• Takes 2 arguments.

• Both arguments have to be numbers or a variables.

Input Example:

// variable input

input = 6

// [function] --> [output]

4*2             --> 8
{input}*2       --> 12
5*(-2)          --> -10

5*(-2)          -->     68779267

Combining Function Operators

You can combine basic operations to create more complex expressions using parentheses (). For example:

// variable input

input = 6

// [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

You can also use arithmetic operations in conjunction with other functions:

// [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
