Summary0030355: Enums: enumeration value is truncated to signed int32 value, not documented and can cause unexpected results
Descriptionenumeration values are truncated to signed int32 values which can give unexpected results, eg
enum ENUM {
    a = 0x80000000,
    b = 5000000000
};

var a = 0x80000000;
var b = 5000000000;
( a == ENUM.a ) is false ( a is 2147483648, ENUM.a is -2147483648 )
( b == ENUM.b ) is false (ENUM.b is -2147483648 )

documentation does not mention this behaviour and currently states re enum values : "This value can be any integer number that a floating point double precision number can represent" which is incorrect.

Fixed in gitlab - internal table truncated enums to int's... this has been corrected...
