Returning SNMP float values?

I've managed to return string values, integer values, and boolean values (as
integers). I'm trying to return float values. The nearest thing I see is a
Float type defined in UCD-SNMP-MIB, defined in terms of an Opaque type, in
SNMPv2-SMI. Opaque is defined as "IMPLICIT OCTET STRING". I guess that means
if I want to return a floating type, I return it as a string, with something
like this:

/* mystr is an allocated string buffer
 * myfloat is the float I want to return */

sprintf(mystr, "%f", myfloat);
snmp_set_var_typed_value(var, ASN_OCTET_STR, (u_char *) mystr, strlen(mystr));

Is that right? Thanks.
