# Maths & Operators

From COD Modding & Mapping Wiki

Maths is used throughout scripting to get many different values, be it the distance between two objects or to calculate an equation.

## Maths & Operators

For example, a variable can be given data from an equation.

variable = 5 + 1;

Although the above example is pretty pointless, as it adds one constant to another to make a constant, and you can just calculate it yourself and use the answer i.e.

variable = 6;

But variables can be calculated using other variables, for example...

varAnswer = var1 + var2;

varAnswer will be equal to the value of var1 plus the value of var2.

There are several operators that can be used in maths...

+ :: Addition - :: Subtraction * :: Multiplication / :: Division % :: Modulus = :: Equals

There are also some more little-known operators such as...

++ :: Increment (+1) -- :: Decrement (-1) += :: Incrementation (requires number) -= :: Decrementation (requires number)

Example of these in use...

var++; //Set var to var + 1 var--; //Set var to var - 1 var += int; //Set var to var + int var -= int; //Set var to var - int
