One thought:

    if (!NIL_P(val = rb_check_convert_type(arg1, T_STRING,
					   "String", "to_str"))) {
	foo(RSTRING(val)->ptr, RFLOAT(rb_Float(arg2))->value,
	    RFLOAT(rb_Float(arg3))->value);
    }
    else if (!NIL_P(val = rb_check_convert_type(arg1, T_FLOAT,
						"Float", "to_float"))) {
	foo(RFLOAT(val)->value, NUM2INT(arg2), NUM2INT(arg3));
    }
    else {
	rb_raise(rb_eArgError, "unsupported argument %s",
		 rb_obj_classname(arg1));
    }
