Variable Explanation

Variable types:
integer - number with no decimal, for example 15
float - number WITH decimal, for example 15.86
string - Text string. For example hello
constant - same as string, however, it cannot be changed (const greeting = "hi" is correct, but you can't change it later.)
vector - A variable that hold different values ( myvec(1) = "hej" etc)
