When entering a value greater than 2^53+1 the number is converted into a string, but is still limited by the precision of the equivalent double value. For example, 9007199254740993 will display as a string (green in the property field), but will display 9007199254740992 on the screen.
@pturmel You can’t type in a string of numbers larger than 2^53+1 without it being subject to floating point precision. Further, it appears that ignition understands that it can’t represent this value as a number, so it converts to a string, so something seems to be wrong with how it gets interpreted…
