The HP 300s+ is a non-RPN scientific calculator meant for
(high school) students. It has TFD (Textbook Format Display) which
means that results are displayed as accurately as possible on its
four lines, 15 characters display (dot matrix, 31 x 96 pixels). The
calculator can be set to either "Mthlo" which implements said Textbook Format Display,
or "linelO" which displays all results numerically.
This calculator is not produced by HP itself but under licence by Moravia Consulting. They produce other HP calculator models as well. Their page on this calculator can be found here (link valid 2024-07-27). Parenthesis do not need to be balanced. When pressing the "="-key all open parenthesis are presumed closed. Also, multiplications are implied when for instance entering "2sin(45". When an error occurs, or when one wants to edit a previous calculation, simply press one of the arrow keys "◄" or "►" to edit it. The "CALC"-key makes this calculator semi-programmable. It works as follows. Enter one or more of calculations using variables separated by colons (up to 99 steps). When the "CALC"-key is pressed the calculator will query for the values of the variables and after pressing "=" will show the results of the entered calculations. Using the "CONV"-key, numerous unit conversions are possible. RanInt% can be used to play dice, "RanInt# (1,6" will randomly display a number within that range. Press the "="-key to throw again! All in all, this seems to be HEWLETT PACKARD’s answer to the CASIO fx-82 and the TI-30 series of calculators, with many of the same functions and keys. Very useful calculator nevertheless. |
