Low frequency counting

Hi Folks, I am using the T7-Pro to generate a low frequency pulse for driving a pump (one falling edge per revolution on this control board) and I am testing over the range [1.0 1.5 2.0 2.5 2.9 3.0]. When I use the example file for PWM and counter (thanks for that, really nice and clear) it will not read back the fractional frequencies. Is there a way for me to get what I want, i.e. a readback from a counter with a float rather than an integer looking answer?

Here is my table of values for reference:

 For DIO_EF_CLOCK#_DIVISOR = 256
    =====================================
    DIO_EF_CLOCK0_ROLL_VALUE     FREQ OUT
    104166.66                    3
    107758.62                    2.9
    125000                       2.5
    156250                       2
    208333.33                    1.5
    312500                       1    

Not that it should matter, but I am doing this all in Python 2.7. Independent verification with "nScope" shows the pulses are right on with respect to my fractional values, only the counter is reporting incorrectly.

Thanks,

JF
