hello guys i just have problem with $calc identifier
for what reason this don't work?

Code:
//echo -a substract $calc(900000186448273800000000 - 1)
//echo -a add $calc(900000186448273800000000 + 1)


the $calc identifier don't substract 1 to the 900000186448273800000000 amount or amounts bigges. I have a money system on my bot and when i try to add small amounts to large amounts or small amounts subtract large numbers.


So my question is: this is a bug? i try to do that operation using /inc & /dec commands and not working too. someboy have a fix for that..?

Thanks in advance
