  • Reciprocal of a Number

    Hello,

    I am creating a report and I need to calcualate the reciprocal of a negative number. Can anyone think back to their algerbra days and tell me how I can come up with the reciprocal of 10.00- which would be 10.00.


    Thanks,

    DAC

    I thought reciprocals only deal with positives to fractions and back again.

    are you saying if the number is negative youd like to see it as positive

    if so then

    if number is less than *zeros
    number *= -1
    endif

      I thought the reciprocal of -10 = -.1 = 1/-10?

      If you are looking for the absolute use:
      PHP Code:

      number 
      = %Abs(number) ;

        From Wikipedia,

        Reciprocal (mathematics), the number 1/x, which multiplied by x gives the product 1

          Now class.... let's get back to basics...

          1 + 1 = 2
          2 + 2 = 4
          3 + 3 = 6
          ...

            We've had this discussion before! You know the one. About how subtracting a negative from zero gives the same result as multiplying by negative one, but at a fraction of the cost!

            Code:
            if number is less than *zeros
              number = 0 - number
            endif

              Personally I would move all numbers into a large character field then search the character field for a minus sign. If you find one, change it to a space and then move the entire field back into a numeric.

                  You're right. That is the reciprocal of -10.00

                    I thought you multiplied it by 100.000001... or was that something else... heh
