The size of integer that can be handled depends on whether Max is operating in 32 or 64 bit mode. To see the difference, enter a ridiculously high number, like 7245569558. The integer number box may have changed to -2147483648. How did that happen? Integers always have a limit – in 32 bit mode, the maximum value of an integer is 2147483520. In 64 bit mode, the top value is 9223372036854775807. Any numbers greater than that cause the integer value to "overflow", and become the greatest negative number. Other very high values might provide other values, depending on how far over this limit the number is. The range of floating point numbers is approximately 38 digits in 32 bit mode and 308 digits in 64 bit mode.
