Hi,

I am having problem with floating point operation. whenever I perform the following codes I get the error mentioned later.
///////////////////////////////////////////////////////////////////////////////////////
float a = 1.0, b = 2.3;//global var
a = a + b;
///////////////////////////////////////////////////////////////////////////////////////
Message #0
Message: FUN: bad bit number
SAT: bad bit number
FOV: bad bit number

RND: bad bit number
Need help, soon, thanks in advance.

I couldn't get this message. The code I used for testing is:

Code: Select all

float aa = 1.0, bb = 2.3;


void main() {
  aa= aa + bb;

}//~!

Which PIC do you use? Some PIC18s have a pre-defined constant a.

Hi,
Thanks for the reply. The PIC I am using for the code is PIC16F870 and for that even ur sample code does not work I have tried it totally in a new C file. Please let me know what to do. Thanks,
Imran.

I forgot to mention the Srystal speed in the previous message it is 4.0000MHz.

There is a similar type error in case of casting see the following screenshot.

Which version of mikroC do you use (if it is not 2.0.0.3 latest, please download it and give it the try).

One more possibilty is that search path for the project get corrupted.
Go to options->search paths
And Then:
1.(if you use p16 family)
if there is any path to ..\uses\p18 please remove it

2.(if you use p18 family)
if there is any path to ..\uses\p16 please remove it

[imyousuf]

Options-->Search Path does not have any .../Uses/P18/ and my version is 2.0.0.2, did it have this error before? Do I really have to upgrade?

Do I really have to upgrade?

Please do. You could wait for another day or two for version 2.0.0.4 to become available, but you should always upgrade to the latest version, especially for the minor releases that mostly do the bug fixes.

Hi Everybody,
The Floating Point Arithmatic problem does not occur in the Current available version (2.0.0.3). Thanks for all the help,
Imran.
