#89497 - Handling real numbers |
I am making a pulse counter using AT89C2051 uC. Apart from counting pulses I also have to solve an equation of the form:
Displacement = ((No. of pulses)/PPR) * (Pitch). The default values of PPR and Pitch are 50 and 5 resp (both whole numbers). However, Displacement may be a real number. Now, the problem is "I don't have much experience programming in assembly and I wonder how to get Displacement as a real number and what would be an appropriate format to store Displacement" Further complications arise because I have to display Displacement using 7-segment display ( with BCD to 7seg drivers) and I also have to send this value via serial port to a PC. I am not looking for readymade solutions but guidelines. Kindly. assit me by providing useful tips and relevant refrences (online articles, preferably). Regards. |
