why would this floating not count.
I know it's something with decimal place to do. It is counting fine, until it comes to five decimale in front ofthe point
Sorry for my bad english

Please review this information. I believe that you are exceeding the value for the register.

32-bit floating point is limited to seven significant digits. It doesn't matter which side of the decimal point.
If you require three digits to the right of the decimal point, the largest value you can accumulate is 9999.999. Once your accumulated value exceeds 10000.00 your smallest increment becomes 0.01.
