    multiplication with fractions

    gopalakrishnan.varadappan.2

      i am tring to measure pulse rate by gating the the input pulses for a fixed time (0.5 mS) by using a 16 bit gating timer(T1) and the incoming pulses are counted by a 16 bit counter(C1). I noticed an error in the pulse count.  Eigther by reducing the gating time or multiplying the result with some fraction i may get the corrected resul like that i thought.

         

      When i tried to multiply the counter's result with a fraction i couln't get the correct result. (i defined the counter's result as int variable).  could you please suggest?

         

      regards,
