%b formatter outputs hex constant
OD 2020.1, 64-bit Linux
format-out("%d", -9223372036854775808) produces no compiler warning and outputs #exFFFFFFFFFFFFFFFF8000000000000000.
I'm not even sure what #ex... is, but I'm pretty sure it's not a decimal number.
(That numeric constant is -2^63 and doesn't fit in 62 bits.)
Same output for %b.
It seems like there are two things here. The constant should be flagged as not fitting in an <integer> and whatever that currently ends up turning into (a machine word?) the formatters should signal an error if they can't handle it, or they could do what Go does and output something indicating a bad input: !%d<the output as rendered by %=>
#e is from Gwydion, representing <extended-integer> (bignums), and is (I think) representing a <double-integer> in this case.
