Max char length in variable

[am632]

Hi,

Just a general question, I'm trying to write a calculator for a specific sum but came across a problem.

Question is, what is the max amount of characters in a string of chars that can be assigned to a variable?

for example the issues i'm having are as follows.

If I have the code...

Local $var = 1001011001010100001

msgbox(0,"",$var)

the message box displays 1001011001010100001 as expected.

But if the string is slightly longer such as...

Local $var = 1001011001010100001001001000100100

msgbox(0,"",$var)

I get the following in my message box, 9223372036854775807.

If I wrap my number in "" then the message box displays correctly.. example

Local $var = "1001011001010100001001001000100100"

msgbox(0,"",$var)

However if my string of characters is too long, autoit returns an error of 'Unterminated string'.

Is this a limitation of AutoIt? I'm trying to work out a sum but none of my calculators can display enough digits and they all just give an error.

In your examples you assign a number to a variable, not a string type and the large number exceeds what the upper limit of a signed 64-bit integer. Now if your last string is too long, it exceeds the line size limit of the interpretor, 4096 characters. Use continuation:

Local $str = "abcdef01234567890123456789" & _
             "0123456789 continuation line!"
