HPC The main difference is the smaller memory of only 2 kByte. Manuals At least four editions of the Reference Manual exist: Version 1 dated October to version 4 dated November HPS Direct-Key Commands General The following section gives a description of useful commands that are directly accessible from the keyboard. Symbolic solver for quadratic formulas. USER Display user variables and progams in the current directory. Note that different from other HP calculators this does drop the stack.

Percentual difference from contents in stack level 2 to contents in stack level 1. It is stack based with a support for many data types.

Later models like the HP and HP used it as well. Note that you cannot put a complex number into a real matrix! Vector and matrix indices count from 1. HPS Returns the residual: A must be a matrix; B and X must be of the same type, either matrix or vector. HPS Select decimal entry format and display all binary numbers in the stack in decimal notation with a trailing ‘d’.

Select hexadecimal entry format and display all binary numbers in the stack in decimal notation with a trailing ‘h’.

Select octal entry format and display all binary numbers in the stack in decimal notation with a trailing ‘o’. Note that either a space hp28ss the delimiter symbol either dot or comma, depends on the current RDX setting can be used to separate the real and imaginary part. HPS Note that the command does not accept binary numbers!

List indices count from 1 and must be within range. Note that this is an overwrite operation, not an insert! Inverse operation of PUT: MANT Mantissa of a real number. Manial Exponent of a real number. Integer part of a real number. Fractional part of a real number. However, there are important differences: Practically, the number is limited by the available memory.

HPS This command can operate on lists of names. MENU Creates a customized user menu. ORDER Takes a list of variable names and moves these names in the given order to the beginning of the current user menu. Np28s also an interactive equation editor available FORM.

If flag 36 is clear the “numerical” evaluation mode is used. It evaluates expressions until a numerical result has been found. If an undefined variable is encountered an error is issued. HPS The presence of the following commands depends on the type of the current subexpression: Replace exponentials of an exponent by a product of exponentials: Statistics functions cannot operate on complex data. Hold down “ON”, then press “L” Prints the entire character set until the printer is turned off.

Print object in stack level 1. With STEP the loop counter is incremented by “step-size” and the loop stops when the loop counter exceeds “end”. Lists and programs are assumed to be identical when they contain the same elements. Use STOP to halt the scan. Not available on all HPS versions.

To the left positive powers and to the right of it negative powers of units are assumed. It displays all non-0 fractional digits of a number. Note that a change of the number format affects the display of manyal values in the stack. This includes plain numbers that occur within programs or lists. Hhp28s Arcus sine of a real or complex value. Cosine of a real or complex value. ACOS Arcus cosine of a real or complex value.

Tangent of a real or complex value. HPS The solver finds a solution for x or y where the left side equals the right side.

The solver finds the value for one of the variables used in the program X or Kanual for which the program returns 0 in stack level 1. A root has been found. Two adjacent points have been found where the function changes it sign. Possibly, the function has a discontinuity at this point. HPS the plot axes. The form of the function determines how it is displayed: HPS cursor over the plot.

INS can be pressed repeatedly to digitize multiple points. PIXEL Takes a complex number from the stack and sets the pixel specified by the real part horizontal position from left and imaginary part vertical position from bottom.

The current coordinate system settings in PPAR are obeyed! If the x and y positions need to actually refer to raw LCD pixels originating at the bottom-left corner then enter: In addition it is possible to specify derivatives for user-defined functions which the differentiation algorithm will use to generate complete differentials.

Each argument in the original function produces two arguments to the derF function.

Further evaluation results in ‘derF X1,x2,0,0 ‘ if neither variable X1 nor X2 exists. HPS Double space printing. Decimal sign MODE menu: If a period is used as the decimal sign then the comma will function as number separator — and vice versa! When set a BEEP occurs for every keypress. Addresses change between different versions of the HPS software. Calling an invalid address usually resets the machine and causes a “Memory lost” error.

Programs General information on programs Menus in the order of appearance on the calculator Page of 49 Go. Famous calculator made by Hewlett-Packard from — Note that a program or other lengthy.

The main difference is the smaller memory of only 2 kByte. At least four editions of the Reference Manual exist: It is best described by edition 4 of the Reference Manual. Commands can be entered by typing their name explcitly. Most commands and functions are organized in menus, some are.

See Direct Key Commands. Table of Contents Add to my manuals Add. Alphanumeric full performance programmable calculator pages. Page 11 HPS Select decimal entry format and display all binary numbers in the stack in decimal notation with a trailing ‘d’. Page 18 HPS This command can operate on lists of names. Page 21 HPS The presence of the following commands depends on the type of the current subexpression: Page 22 HPS 0. Print Menu 10 different elements if the order of the drawn elements does matter.

Logs Menu usually complicated functions. Page 37 HPS The solver finds a solution for x or y where the left side equals the right side. Page 40 HPS the plot axes. Page 41 HPS cursor over the plot.
