maybe.

Good Morning.

Full is a bug this xHarbour because this returning garbage in decimals.

It is good to inform xHarbour developers.

bye.

No, it's the normal behaviour of the floating-point numbers.

Enrico understood, then the solution would be to truncate the decimals?

I did not understand what the problem is that this variation is causing him.


Thanks

Better to round it to the desired number of decimals using ROUND() function.

It works simple. You never come to 8.8

local n:=8.8
MsgInfo(str(n,20,18))

Clipper, Harbour, xHarbour floating-point system supports up to 15 significant digits.
