Hay all,

Dose Anyone know If the PAK-II can do this math problem?

7501876 / X = Y

Where X can be anywhere from 750 to 65535
Also can anyone give me a simple source code for a bs2

Also about how long would it take to do that problem and this one? ( guess-ta-mint )

P x 3600 / M

Where both P and M are word size

thanks

TC

    Yes. Without testing it, the code would look something like this (using the
    PAK-II library that is included):

    gosub freset ' reset PAK-II (one time)
    fpx=x
    gosub floadint ' PAK2_X = stamp_x
    gosub fxtoy ' PAK2_Y=PAK2_X
    fpxhigh=$9564
    fpxlow=$F068
    gosub floadx ' PAK2_X=7501876 (this # comes from FConvert program
    included)
    gosub Fdiv ' PAK2_X=PAK2_X/PAK2_Y
    gosub FInt

    ' 24 bit integer result in fpxhigh, fpxlow or since you only need 16 bits:
    y=fpxlow

    For the second problem:
    fpx=M
    gosub FloadInt
    gousb FXtoY
    fpxhigh=$8A61
    fpxlow=0 '3600 (from FConvert)
    gosub floadx
    gosub fdiv ' X=3600/M
    gosub FXtoY
    fpx=P
    gosub floadx
    gosub fmult ' X=X*Y
    gosub FInt ' read integer result
    result=fpxlow '(16-bit result)

    The hex numbers come from the FConvert program that appears on the disk or
    you can download it from the main page of the website

    Hope that helps.
