visible floating point issue

I have a process control system running on 6.2 using the latest version of FreeAxp.

This system has some UI where values between 0.0 to 100.0 are entered. Whenever a 100.0 (%) is entered, an error comes up informing the user that an invalid value was entered; that is, the value is outside the 0.0 - 100.0 range. 99.99 has to be entered which is then coverted to 100.0 when the dialog is re-opened.

This might be a minor issue but from the user's point of view this is a big problem.

Note that this doesn't happen with PA.

Just to confirm, you are running 1.0.8.283, correct?

Would it be possible to supply the code or a sample program demonstrating the problem?

i'm on 288.

i'll try to recreate the issue as i don't have access to the source code.

Hello Bruce,

The original program was created using fortran and this sample fortran code mimics what the UI response is when a value of 100.0 is entered.

This is the output from PA:
< class='quote'>
( 9.900000 ) 99.00000 is ok
( 10.00000 ) 100.0000 is ok


And this is the output from FreeAXP:
< class='quote'>
( 0.900001 ) 99.00001 is ok
( 10.000000 ) 100.0000 &gt; 100.0


This example gives a weird result.

PA output:
< class='quote'>
100.0000 , 10.00000
99.99000 , 9.999000
99.99990 , 9.999990


FreeAXP output:
< class='quote'>
100.00000 , 10.000000
00.99000 , 0.999000
00.99990 , 0.999990


BTW, I'm using 6.2-1H2.<hr>

Thank you. We will check into this.

Your contribution allowed us to isolate the floating point issue. Thank you! We will issue an updated kit soon.
