It would then have ZERO impact on the runtime, not even new library routines, and still let (...) (26 years ago, 5-May-99, to lugnet.robotics)

Since Java doesn't support operator methods you have clunky syntax (...) (26 years ago, 5-May-99, to lugnet.robotics)

| | | | | | | (...) I see what you like about having a FixedPoint type and being able to say a = b.Multiply(c) This gives you the flexibility to add modules as you need them by dumping all the work onto the compiler, which is not a bad place if you are not the (...)

Assuming the language has the flexibility, you could certainly do the FP emulation in the library as well. However, you lose the ability to take (...) (26 years ago, 5-May-99, to lugnet.robotics)
