measureValue = 23451.123;
os_sprintf( measureValStr, "%f", measureValue );
os_sprintf( tempStr, " kWh");
strcat( measureValStr, tempStr );
os_printf(" measure str is %s \n", measureValStr);


but the result is " %f kWh" , why not support this format ?
I want to use C API sprintf, but compile error
Need your help, thanks.
