Math.Random return -2147483648

[mslight13]

Hi all,
I'm trying to use 'Math.Random' action to generate 10 digit random number but it returned -2147483648.

I think the digits of generated number in 'Math.Random' action is limited.
Is there anyone to help me for solving this problem?

Unless you use external libraries, you may see this happening, as the big number causes an overflow. However, you could easily write your own random number generator, if you really need big numbers, for example:

function Math.BigRandom()
	local nRand1 = Math.Random(0, 99999);
	local nRand2 = Math.Random(0, 99999);
	return string.format("%05d%05d", nRand1, nRand2);
end

Thanks Ulrich,
Can you give me more information about string.format? I can't find it in Action Wizard...

I suggest use all of the LUA functions and modules in next version of AMS (in Action Wizard) or put a description in AMS help file.

Indigorose is not responsible for documenting Lua functions. Lua is a standalone scripting engine which is used in AMS, you can read up on all the Lua 5.1 functions in the Lua 5.1 reference manual.
