Operation Ultimate implements arithmetic operations on scalar values (56.9e+3), values with units from a combination of user-defined base systems (6KgM^2), values with derived units (6.3Mph), and any legal combination of these options. User-defined named constants (Pi) are also supported. The unit base systems (1 2 3 4) can be defined in terms of currency, temperature, weight, mass, pressure etc.

 Values are represented as C++ 64-bit floating-point values.  Values are entered on a last-in-first-out stack as they are keyed.  All operators ( + - * /) are applied to value(s) removed from the top of the stack and then place their result back on the "top" of the stack.  For example 4 enter 5 enter +, places 4 then 5 on the stack, the addition operator (+) removes 4 and 5 from the stack, adds them together and places the result (9) back on the stack. Ultimate also supports infix expressions (3+4*5 enter == 23).

Key Buttons Ultimate is designed for stylus-only use, but data can also be entered from a keyboard.

0-9  

Enter a digit

  .  

Enter a decimal point (only one per number)

  e  

Used for scientific notation 1.3e2 == 1.3*10*10 == 130

CE  

Clear Entry, if entry is already clear, pops top of stack

  <-  

Erase one character

Enter  

Put value in window on top of stack

  + - * /

 Add   Subtract   Multiply   Divide

  (   )

 Change order of operations 3*5-2 == 13 while 3*(5-2) == 9

A B C D

 User-defined buttons

X Y Z

 X refers to the first value pushed on the stack, Y 2nd, Z 3rd

 

 3 enter 4 enter x*y-7 enter == 3*4-7 ==5

  ^

 Value and unit power operator 3^4 == 81   6M^2Sc^-3

Menu Options Ultimate supports the input of user-defined parameterization files, which can be tailored for personal preferences.  Definition files are plain text.  A sample file (calc.txt) is included in the Ultimate distribution.
