Version History


V6.4
  • There are now two Algebraic Modes (Prefix and Postfix). Prefix allows you to enter calculations as you would read them. Postfix allows you to enter numbers first, then the operation.

 

V6.3
  • Algebraic mode now more closely matches traditional-style entry. Calculation expressions can be entered as you would read them. You can now enter 3sin(45) as you see it.
  • Complex i and all constants (like π) are now treated as variables. You can now enter as you see it. This also works in RPN mode.
  • Operator precedence has been lowered for functions MOD, NCR, NPR and Δ%. This more closely matches industry-standard computational engines. They now sit just below the S in PEMDAS.

 

V6.2
  • MOD is now extended to Complex Numbers.
  • Improved a lot of expression logic.
  • Updated the text on a few shifted buttons.

 

V6.1
