Constants



 PG Calculator offers a list of common used mathematic, physic and chemical constants. Please use [APPS] key and select "1.CONSTANTS LIBRARY" from menu:



 You can move through list of constants using direction key [UP] and [DOWN]. To select constant press [F6] or [ENTER] key.



 If your current working mode is RPN selected constant will be putted to the stack. If you work in algebraic mode selected constant will be putted into the expression at position indicated by cursor.

 Below you find the list of defined constants in PG Calculator:
