silly question - large numbers

[slugger]

im having an issue, simple really. im sure im being a bit stupid.

i am incrementing a large number to an indicator i/u64 but when it it gets to about 2 billion it goes negative.

im sure it should be a bit bigger than that.

if not, how can i get the indicator to increment into the tens of billions

regards

Hi slugger,

such questions are answered best with an example VI of yours…

I64/U64 should allow a much larger range than ~2e+9 - infact in the order of 1e+19!

So it seems you used an I64 indicator but you still calculate using I32 values…

im getting number of bytes written from tcpip write then via a shift register am adding on each loop.

im guessing the shift register is 132? or the addition?

hmmm just checked it

my addition was I32

many thanks

wouldnt have guessed that for a bit !!!!

many thanks

If GerdW solved your issue, it would be nice to give him credit in the form of a marked solution.  🙂
