os_sprintf function donot support format parameters for float type

[sdylion]

Hi,
I want to use os_sprintf function to convert float to string ,why not support "%f" or "%10.3f", the code like this :

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.
