Usage
the maxInteger
Description
System property; returns the largest whole number that is supported by the system. On most
personal computers, this is 2,147,483,647 (2 to the thirty-first power, minus 1).
This property can be useful for initializing boundary variables before a loop or for limit testing.
To use numbers larger than the range of addressable integers, use floating-point numbers instead.
They aren't processed as quickly as integers, but they support a greater range of values.
Example
This statement generates a table, in the Message window, of the maximum decimal value that can
be represented by a certain number of binary digits:
on showMaxValues
b = 31
v = the maxInteger
repeat while v > 0
put b && "-" && v
b = b-1
v = v/2
end repeat
end
