simple calculations

[awandering]

i am trying to do two equations:

1st : (value1 * value2)/2 //shear in a beam
2nd : (value1 * value2^2)/8 //moment on a beam


My code look s like:

float	temp_mqk,
			temp_mgk,
			temp_length;
	temp_length = record[member_no].member_length;
	temp_mqk = record[member_no].member_qk_factored_load;												//assign struct memebr qk factored load to temp float
	temp_mgk = record[member_no].member_gk_factored_load;												//assign struct member gk factored load to temp float
		record[member_no].member_max_moment = (((temp_mqk+temp_mgk)*(temp_length*2))/8);					//determine max bending and assign to structure
	record[member_no].member_shear = ((0.5)*(temp_mqk+temp_mgk)*(temp_length));								//determine shear value and assign to structure
	member_details_save();	

However the values are not calculating correctly

any ideas??
