PB.Ex Math (Windows)

[RSBasic]

Hello

With this library it is possible to write arithmetic operations and paths in a string and have them calculated by the library. All basic arithmetic operations and other operations are supported.

Functions:

• Calculate()
  • Syntax:

    Code: Select all

    Result = Calculate(Calculation$, @ErrorOutput$)

  • Description: Calculates the given mathematical task.
  • Parameter:
    1. Calculation$: The following operations can be used: + - ± * / % ^ e == != > >= < <= ! && || pi sqrt() abs() round() min() max() ceil() floor() trunc() log() log10() cos() sin() tan() acos() asin() atan() cosh() sinh() tanh() deg2rad() rad2deg() rand()
    2. @ErrorOutput$: If an error occurs, the error message is stored in the string variable.
  • Return value: The result is returned as a double value.
  • Example:

    Code: Select all

    EnableExplicit
    
    Global PBEx_Math
    
    CompilerIf #PB_Compiler_Processor = #PB_Processor_x86
      PBEx_Math = OpenLibrary(#PB_Any, "PB.Ex_Math_x86.dll")
    CompilerElseIf #PB_Compiler_Processor = #PB_Processor_x64
      PBEx_Math = OpenLibrary(#PB_Any, "PB.Ex_Math_x64.dll")
    CompilerEndIf
    
    If PBEx_Math
      Prototype.d Calculate(Calculation.p-Unicode, ErrorOutput)
      Global Calculate.Calculate = GetFunction(PBEx_Math, "Calculate")
      
    EndIf
    
    Define ErrorOutput$ = ""
    
    Debug "1 + 2 - 1 = " + Calculate("1 + 2 - 1", @ErrorOutput$)
    Debug "2^32 = " + Calculate("2^32", @ErrorOutput$)
    Debug "5 + 2 * 2 = " + Calculate("5 + 2 * 2", @ErrorOutput$)
    Debug "(10 + 20) * 10 = " + Calculate("(10 + 20) * 10", @ErrorOutput$)
    Debug "pi * 4 = " + Calculate("pi * 4", @ErrorOutput$)
    Debug "2.5 + 10 = " + Calculate("2.5 + 10", @ErrorOutput$)
    Debug "Modulo = " + Calculate("2 % 1 == 0", @ErrorOutput$)
    Debug "AND condition = " + Calculate("1 == 1", @ErrorOutput$)
    Debug "sqrt(64) = " + Calculate("sqrt(64)", @ErrorOutput$)
    Debug "round(5.4) = " + Calculate("round(5.4)", @ErrorOutput$)
    Debug "is 5 ot 10 greater? = " + Calculate("max(5, 10)", @ErrorOutput$)
    Debug "15 > 10? = " + Calculate("15 > 10", @ErrorOutput$)
    Debug "sin(1.5708) = " + Calculate("sin(1.5708)", @ErrorOutput$)
    
    CloseLibrary(PBEx_Math)
    

If you want to have some additional functions besides this one, which do not exist in PB, just suggest them.

Systemvoraussetzungen:

• Windows Vista oder höher
• .NET Framework 4.5 oder höher
• Unicode-Aktivierung (standardmäßig ab PB 5.50)

PB.Ex Math 1.0.1.0 has been released.

Changelog:

• Changed: Calculate(): There is no longer case sensitivity.
• Bugfix: Calculate(): If an error occurred, then other calls also failed.

[RSBasic]

PB.Ex Math 1.0.2.0 has been released.

Changelog:

• Changed: Calculate(): Negating with the minus sign is now possible.

very useful
It should be integrated into PB.
thank you

If someone wants cross-platform PureBasic source code (strictly tested), see e.g. here:

Great, thank you for sharing !

I recommend the code by Little John. This project is discontinued.
