Is this a bug with "printf()" and "fprintf()"in open C?

Hi,

I just found a problem when using "printf" function in Open C using N95. If anyone can help me, please advice.

Say I want to display some vairables' value with the following code:

double x = 9.0
float y = 8.005;
double z = 4.01;

printf("x = %f \n", x);
printf("y = %f \n", y);
printf("z = %f \n", z);

Instead of showing the exact value, the output is actually shown as the following:
x = 9..000000
y = 8..050000
z = 4.0100000

For some reason, two dots are displayed for some variable (i.e. x and y).

You can easily repeat the problem. Just create a regular symbian project in Carbide C++ and then put the above code somewhere. I put the code in the application view constructor.

The same problem also occurs when using fprintf(), which prevents me from saving float point data into a text file correctly. If anyone can give me some advice, I'd be very thankful.

Hi,

This is definitely a bug. A new version of Open C is due out very soon. If it's still broken with that then you should report it as a bug.

In the mean time, I think your only alternative is to convert the numbers to strings yourself and print those.
