I have mqx 4.0.1 installled on my device. I am using its web server.
When sending the data from device to web browser I am using sprintf at several places in device side C code.
I am using sprintf to copy float values into a character array as below:
sprintf(MyArray, "%5.3f", f_Value);
The float value is first read into variable "f_Value" and then I am using sprintf() as mentioned above to copy the float value into buffer "MyArray".
The value that is read into variable "f_Value" is correct.
But when I use sprintf() to copy it to "MyArray" then sometimes a garbage value(18434449246735240000000.000) gets stored in "MyArray".
Sometimes if variable "f_Value" is having value say 100.000 into it; then after copying it to "MyArray" using sprintf() shows value 0.000 into " MyArray".
Or sometimes a random character like "/" appears in "MyArray".
I tried using snprintf as below but still same issue is observed.
snprintf(MyArray, sizeof(MyArray), "%5.3f", f_Value);
Please let me know if you have any solution to fix this problem.
