Basic Operators¶. In order to be notified when either thumb value changes, register for .ValueChanged: On 32-bit platforms, Int is the same size as Int32, and on 64-bit platforms, Int is the same size as Int64. When a function is newly defined, it may take one or several values as input 'parameters' to the function and it will process the functions in the main body and pass back the values to the functions as output 'return types'. More specifically, you can use Int32, Int64 to define 32 or 64 bit signed integer, whereas UInt32 or UInt64 to define 32 or 64 bit unsigned integer variables.
