Vm molar volume of ideal gas NA Avogadro's number e elementary charge me electron mass mp proton mass mn neutron mass R h k molar gas constant Plank's constant Boltzmann's constant Probability Pressing P displays the Probability menu, with the following functions: nPr nCr !RANDM RANDMI Calculates the number of possible permutations of n items taken r at a time. Calculates the number of possible combinations of n items taken r at a time. Calculates the factorial of a specified positive integer n, where n <= 69. Creates a random real number between 0 and 1. Creates a random integer between (and possibly including one of) two specified integers. Meaning 2nd set of function keys is active (see below). Numbers are displayed in engineering notation. Numbers are displayed in scientific notation. Angle setting is degrees, radians, or gradians respectively. Number of decimal places displayed is fixed. Hyperbolic trig function will be calculated. There are digits to the left or right of the display. There are earlier or later results that can be displayed. Result is negative, or the entry line is full. A constant expression can be defined or used. Result is displayed in scientific or engineering notation. Thousands separator (for numbers >= 1000).
