An IP address stores key information, like the network the device is linked to and details of the device itself. To understand subnets, you’ll first need to understand IP addresses.

APCALCULATOR PLUS
If you’re interested in checking out an excellent subnet calculator, I recommend starting with SolarWinds ® Engineer’s Toolset ™ - you’ll get an enterprise-grade subnet tool, plus other incredibly useful network management features. In this guide, I’ll explain how these automated calculators can help you better understand IP addresses and subnets. What a subnet calculator does differs between tools, which is why it’s so important to carefully consider which subnet calculator and subnet scanning utilities are best suited to you and your organization. Pi, as all integers and rational numbers, e.g one third, are stored as exact rational numbers (exact numerator and exact denominator).Do you use a subnet calculator to help manage your network? An IP subnet calculator is responsible for returning a range of information regarding subnets, subnet masks, network addresses, usable host ranges, IP class, and much more. Note: The internal precision is only limited for irrational numbers, e.g. Time Value of Money.įeatures: Unit conversions, common constants, binary and hexadecimal numeric entry/display, choice of US (period) or EU (comma) radix mark, choice of angle entry (degrees or radians), choice of results display (decimal, scientific, binary, hexadecimal, or a combination of these)
Solve mode is similar to the solve feature of HP calculators, for example allowing solution for any variable even when there is no analytic solution, e.g. In Algebraic mode, all results are displayed to the internal precision. In RPN mode, there is essentially unlimited undo/redo of the entire stack, so that even late recognition of a mistake does not require a complete restart.Īlgebraic mode allows arbitrary expressions to be entered and evaluated. Numeric display, even while entering numbers, features standard digit grouping.
APCALCULATOR SERIES
Initial operating mode is RPN, which approximates the user interface of the HP-48/49 series calculators. Initially set to 64 decimal digits internal precision, with 32 decimal digits displayed, this calculator can be set to any desired precision. In the shortcut’s properties, you may specify another ini file after the path to the executable file.
By default, an ini file named “APCalculator.ini” in the “~/Documents/APCalculator/” directory is applied to initialize APCalc modes and “built-in” function definitions.
The current interface was developed in Qt Creator 4.0.1, based on Qt 5.6.1 (64 bit), and has been tested on OS-X 10.11.ĪPCalc menus are File, Mode, Solve, Equation (Algebraic mode only), Unit, and Constant (more below).ĪPCalc has four basic modes, RPN, Algebraic (Algebraic Interactive), Program, and Solve. This user interface approximates a blend of the features of the HP-42s and the HP-48, but without graphics, statistical, or CAS functionality. All communication with the resulting Calc library is accomplished by function calls with string arguments and string returned values.ĪPCalc is implemented as a Qt-based user interface to the Calc library. The original Calc was modified by eliminating all of the file-based and terminal-based i/o routines. Based on “Calc - C-style arbitrary precision calculator” (2.12.4.14)
