I am guessing there is a bug in b formatting. Note, even base 10:
10b123456789010234567
123456789010234560
10b123456789010234562
123456789010234560
Almost seems like it went "float" internally or some such.

Maybe a better question is why are all of these true?

The byte order the machine is using here is little endian
https://en.wikipedia.org/wiki/Endianness#Little-endian
That means the least significant byte here was 239 (your example) or
240 (my example).
But your number was even and 239 is odd...

I have a 64 bit number:
16b123456789abcdef = 81985529216486896
encoded in 8 bytes in a file:
239 205 171 137 103 69 35 1
but
_3 ic 239 205 171 137 103 69 35 1 { a. returns 81985529216486895 (1 less
than I expected)
16 #.inv 81985529216486895 returns 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
16 #.inv 81985529216486896 returns 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0
I suppose this has something to do with signed 64 bit integers, but I
don't
understand it. I'm running on a Intel machine (Surface laptop).
