Large number

General General RealDash discussion

I have a number consisting of 5 bytes that add up. But Realdash doesn’t seem to understand such large numbers. Because I don’t get the right result. What should I do?

<value targetId="299" units="Km" offset="2" length="5" conversion="(B0*256*256*256*256+B1*256*256*256+B2*256*256<U+202C>+B3*256+B4)/409600"></value>

I calmly deduce four byte run. RealDash understands everything.

I have 5 bytes. The number in dec is approximately 44053905680

4

Unsigned int?
RealDash can up to 65,535 in my opinion this is without math

Try removing your conversion as it is not required when you tell RealDash to read 5 bytes from data and conversion is not doing anything than byte placements.

6

Tell me how to write correctly then, please

7

You don’t have to use the conversion it at all in this case, just remove it.

Try just

<value targetId="299" units="Km" offset="2" length="5" conversion="V/409600"></value>

Still, it seems odd that odometer uses 5 bytes, as it requires 8 bytes to store in memory, and 4 bytes can already display more than 4 billion kilometers. Are you sure you need to use 5 bytes? Maybe you can try to read 4 bytes and disregard the highest byte as you will likely never surpass the 4 billion kilometers hold in first 4 bytes.

this is how many bytes contain the data about kilometers, but there are still two decimal places
