Describe the bug

cast 2d 0x09845e7f93d27198144355dbac3f0cdc34d74f78f40c9a37f0969a924e04c32c returns 4304691653437447671144768329537717612774901428585623103913861666989519717164 however cast 2h 4304691653437447671144768329537717612774901428585623103913861666989519717164 returns 0x9845e7f93d27198144355dbac3f0cdc34d74f78f40c9a37f0969a924e04c32c

However, these two outputs are not equivalent,as the first starts with 0x09 and the latter starts with 0x9

This behavior is also demonstrated in python

>>> a = 0x09845e7f93d27198144355dbac3f0cdc34d74f78f40c9a37f0969a924e04c32c
>>> a
4304691653437447671144768329537717612774901428585623103913861666989519717164
>>> hex(a)
'0x9845e7f93d27198144355dbac3f0cdc34d74f78f40c9a37f0969a924e04c32c'

This breaks expected behavior, for example , method 10 on this contract

(getOperatorFromId)

returns the expected value for 0x09845e7f93d27198144355dbac3f0cdc34d74f78f40c9a37f0969a924e04c32c, and return null for 0x9845e7f93d27198144355dbac3f0cdc34d74f78f40c9a37f0969a924e04c32c

This is also demonstrated when using cast
