[amibroker] Re: [Tomasz] 1 / 0 = 0? : NaN or Infinity would be good

["Mike <mik-u@xxxxxxxxxxx>" <mik-u@xxxxxxxxxxx>]

Hi Tomasz,

NaN or Infinity would be good. I just need something to check an 
exception and get correct value (100) when calculating formula like 
this:

100 - 100 / (1 + 30 / 0) 

Regards,
Mike
