Getting a specific number from a bigger number?

Question

a = (any random number)
Is there a way could I get the third number (12345) without converting it into a string?
If not, what would be a good way to get it by converting it into a string?

Answer 1

You can use the sub function

function getDigit(value,digitPlace) 
return tonumber(tostring(value):sub(digitPlace,digitPlace))
end

This will get the third digit of a as a number:

a = 12345
print(getDigit(a,3))
