 +In previous series of BeBot UserID'​s have been treated as integer values. This has been due to the fact that unlike most other operations in PHP, unpack() does NOT automatically convert numeric values greater than a 32bit integer can handle to a float. As such BeBot allowed the integer to overflow to become a negative signed integer.
 +As of BeBot 0.7.0 this is no longer true. We now handle high UserID'​s as floats, and as such this means special care have to be taken whenever comparing UserID'​s.
 +Do NOT compare UserID'​s the way you would a normal integer, ie 
 +<code php>
 +if ($userid == $userid2)
 +Instead use the bc_cmp function, ie 
 +<code php>
 +if (bccomp($userid,​ $userid2) == 0)
 +bccomp return values are
 +Returns 0 if the two operands are equal, 1 if the left_operand ​ is larger than the right_operand , -1 otherwise. ​
