EuroCalc
EuroCalc for Linux
EuroCalc for Windows

  EuroCalc is a calculator from the collection EuroTool which computes input expression consisting of numbers, operators, functions, and priority parentheses. It calculates mathematical expressions from the command line or interactively in a window.

EuroCalc treats all numbers internally as floating point numbers and it works with 96-bit mantissa and 32-bit exponent.

The input expression can be entered at the command line, for instance
eurocalc 12.345 * (-6.78) + 0x9ABC, optionally followed by equal sign =. EuroCalc will convert all numbers to decimal, remove unnecessary spaces, repeat the corrected assignment and print the calculated result on a new line:

When EuroCalc is run without arguments, it displays a (pseudo)graphic window and it can be used interactively.

Numbers can be entered in decimal, hexadecimal, octal, or binary form and their notation may be mixed in one expression. Accepted notations:

1. Integer numbers
   • Decimal, e.g. 12_345
   • Decimal postfixed with dimension D,K,M,G,T,P, e.g. 12_345k
   • Decimal prefixed with 0N., e.g. 0n12_345
   • Hexadecimal postfixed with H, e.g. 1234_5678_9ABCh
   • Hexadecimal prefixed with 0X, e.g. 0x1234_5678_9ABC
   • Octal postfixed with Q, e.g. 123_456q
   • Octal prefixed with 0O, e.g. 0o123_456
   • Binary postfixed with B, e.g. 0101_0101b
   • Binary prefixed with 0Y, e.g. 0y0101_0101
2. Floating-point numbers
   • FP numbers have one decimal point ., they may be in decimal format only, e.g. 123.45
   • They can be postfixed with E immediately followed with signed decadic exponent of 10, e.g. 123.45E5 or 123E-3.

Parsing algorithmus can distinguish between 123E4h (hexadecimal number 0x123E4) and 123E4 (decimal number 123*10⁴=1230000).

The number format of EuroCalc is compatible with EuroAssembler but it is not limited to 63 bits.

Operation with higher priority are performed first, but the priority may be altered with parenthesis.

All operators and number modifiers are case insensitive. All elements (numbers, operators, parenthesis) may be separated with spaces. The number notation can be enhanced with underscores _ for better readability.
Arguments of trigonometric functions are entered in radians.

Example of using EuroCalc to calculate a SINE function table for angles 0°, 10°, 20°,...90° in Windows:

This linker script is a common configuration and argument processing for both Linux and Windows version.

Both programs in this source file have the name eurocalc . The linked executable file for Linux has the name eurocalc.x and the version for Windows has the name eurocalc.exe.

Both executables will be built with the command euroasm eurocalc.htm.

         EUROASM CPU=X64, Unicode=No, NoWarn=0563
         INCLUDE "argument.htm" ; Assemble the module argument.htm.
         INCLUDE "calcmain.htm" ; Assemble the module calcmain.htm (common for both OS).

↑ EuroCalc for Linux

Linux GUI version works with ANSI terminal in character pseudo graphic mode.

         INCLUDE "calclinc.htm" ; Assemble the module calclinc.htm (Linux console subsystem).
         INCLUDE "calcling.htm" ; Assemble the module calcling.htm (Linux pseudographic subsystem).
eurocalc PROGRAM Format=ELFX, Width=64, Entry=MainCon                 ; Executable Linux file eurocalc.x.
          LINK calclinc.obj, calcling.obj, calcmain.obj, argument.obj ; Program EuroCalc for Linux has four modules.
         ENDPROGRAM eurocalc

↑ EuroCalc for MS Windows

         INCLUDE "calcwinc.htm" ; Assemble the module calcwinc.htm (Windows console subsystem).
         INCLUDE "calcwing.htm" ; Assemble the module calcwing.htm (Windows graphic subsystem).
eurocalc PROGRAM Format=PE, Width=64, Entry=MainCon, IconFile=eurocalc.ico ; Executable Windows file eurocalc.exe.
          LINK argument.obj, calcmain.obj, calcwinc.obj, calcwing.obj      ; Program EuroCalc for Windows has four modules.
