# Simple number formula with unexpected results

## Recommended Posts

for some reason which is beyond me, i seem to be getting incorrect results from this formula

```Global \$odds_arr[1000]
\$COA_num = 1.00

\$COA_int += 1

If you mean that the numbers are out by some very small amaount then that is because of the limitations of computers. The values like 1.45 are converted to a binary value when they are saved and then back when they have to be displayed as decimal. If you want to get results to an accuracy of 0.01 then you will need to add some code to display it the way you want.

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

ive never heard of this sort of limition with numbers before.

```While 1
If \$num <= 1.99 Then
\$num = Round(\$num + 0.01, 2)
EndIf
ToolTip(\$num, 0, 0)
If \$num >= 2 Then
MsgBox(0, "", "yeh")
EndIf
Sleep(10)
WEnd```

seems to do the trick, thanks for your help martin. i thought my autoit installation was corrupt up somethin lol

FYI this thread is one of a few on the accuracy of floating point numbers.
