CW10.4 printf float number?

danielchai — Tue, 23 Jul 2013 12:43:38 GMT

Hi,

I am using CW10.4, k60N512. Now I am trying to print a float number using

printf("Float number is %f\n", fnum);

but it prints"Float number is f".

I read some and configure MQX_INCLUDE_FLOATING_POINT_IO to 1 in smallest_config.h which is included by user_config.h, but it still prints the same content.

I tried to include <stdio.h>, but it give me many errors after I including it in my project.

Is there anything I miss or configure wrong?

Thanks.

-Daniel

Hi Daniel,

Try defining MQX_INCLUDE_FLOATING_POINT_IO as 1 in user_config.h. Then rebuild the PSP.
