Set

Sets a local or global variable to a specified value. This value can be a number or an expression.

Arithmetic Operators:

Operator	Description
+	Addition
-	Subtraction
*	Multiplication
/	Division
%	Modulus (do integer division and return remainder)

Notes:

• A minus right in front of a number or variable acts as "negative"-sign. When you want to do a subtraction, you need at least one space before and behind the minus. This is the only place where you really need a space between arithmetic operators. (For instance: "a-b" will not compile; it needs to be "a - b")

• When using only numbers in a division, you need to use at least one decimal point to tell the game that you want to use floating point division, without a decimal point the remainder is truncated at the end of the division:

float a
set a to 9/5    ; will set "a" to 1.000
set a to 9.0/5  ; will set "a" to 1.800

• When you want to store the correctly rounded result of a division in an integer-variable, you need to make sure, that the calculation uses floating poing (so that the decimal-fraction isn't truncated) and add 0.5:

short a
set a to 9/5          ; will set "a" to 1
set a to 9/5   + 0.5  ; will set "a" to 1
set a to 9.0/5        ; will set "a" to 1
set a to 9.0/5 + 0.5  ; will set "a" to 2
set a to 7.0/5 + 0.5  ; will set "a" to 1

short a
set a to 9
set a to a/5.0 + 0.5  ; will set "a" to 2

short a
float b
set b to 9
set a to b/5   + 0.5  ; will set "a" to 2

Other Examples:

set a to 2
set b to a*a
set c to (b - a)*b - a
set d to ((3* -b+a) - c)/ -2
message "a=%.0f, b=%.0f, c=%.0f, d=%.0f" a b c d     ; ("a=2, b=4, c=6, d=8")
