Number calculation seems wrong

[Dunge]

Not sure why you are converting to binary before calculating the string length, as far as I know it's based on the length of the number directly, not its binary representation. Also trailing 0 should be removed only if they are after the decimal point, not if let's say the number is 1000.

In any case, I have a item that Dynamo report using 10 write unit, but in your tool it report 27 write units and 26657bytes:

Not sure why you are converting to binary before calculating the string length, as far as I know it's based on the length of the number directly, not its binary representation

Should be fixed now by this PR: #7

Also trailing 0 should be removed only if they are after the decimal point, not if let's say the number is 1000.

Not sure I agree. Based on the official docs, all numbers are stored as decimals in Scientific Notation. So 1000 should be in the form as 1E3 (1 * 10^3).

It at most, take up two bytes, one for the significant, and one for the signed exponent. So perhaps, in decimal: 1 131 (3 represented as 131 when signed with the first bit), hex: 0x0183, and binary: 0000 0001 1000 0011

However, It's representation in Dynamo may be only one byte if they are doing something clever with the extra bits (only 7 needed to represent two digits). It wouldn't surprise me if AWS took advantage of any unused bytes to further reduce the size.
