It will only show the first digit after the decimal point.

How can i print 1 decimal place also?

To display a single decimal place instead of two decimal places, replace this line:

Code: Select all

```
snprintf(str2_buf, 20, "%d.%d" , (int)t, (int)(t*100)-(int)t*100); // string with degree C
```

Code: Select all

```
snprintf(str2_buf, 20, "%d.%d" , (int)t, (int)(t*10)-(int)t*10); // string with degree C
```
