BUG? - Round() for negative very small number returns -0

3 posts in this topic

$n = -1 * 1/1000000
 
ConsoleWrite("1 = " & $n & @CRLF)
ConsoleWrite("2 = " & Round($n,2) & @CRLF)
ConsoleWrite("3 = " & StringFormat('%.2f',Round($n,2)) & @CRLF)

result

1 = -1e-006

2 = -0

3 = -0.00

it should be

1 = -1e-006

2 = 0

3 = 0.00

I think it's bug in Round(), it shouldn't return -0 as result in any case.

Should I create bug ticket for this?

I would not necessarily agree that returning -0 is a bug. whether it is -0 or 0 will make no difference to any subsequent calculations. Having the minus sign does let you know that it has been rounded from a number less than 0.

This is not a bug.
