Software designed for website.

Eng-Calculations is a set engineering and technical calculations according to standards for your day-to-day routines. It will reliably, precisely, and most of all quickly guide you through the design of components, the solution of a technical problem, or a calculation of an engineering point without any significant need for expert knowledge.

The user interface Eng-Calculations: Most calculations have a similar user interface, the advantage of which is the logical structure of the task from the top to bottom of the results. So, as you are accustomed to doing, if you solve the task with a calculator on a sheet of paper.

Natural Language Functions: Create and Extend with Ease

Our system allows you to define and use functions in natural language, just like in Excel. With each update, we refine the way functions are interpreted, making it easier to build, extend, and modify them in real time. Define calculations, transformations, and logic using simple phrases, and our engine will convert them into executable functions. Whether for basic arithmetic or complex data processing, natural language functions streamline the workflow for both beginners and advanced users.

Mathematical Constants: Seamlessly Integrate with Your Calculations

Mathematical constants are essential in various fields of science and engineering, and now you can effortlessly integrate them into your work. Our platform supports a wide range of predefined constants like π, e, and the golden ratio, allowing you to use them directly in your calculations. These constants are easily referenced in your formulas, enabling precise and efficient computations without the need to manually input their values. Whether you're working with basic algebra or advanced mathematical modeling, incorporating these constants is now faster than ever.

Sets: Work Within Predefined Number Collections

Our platform offers predefined sets of numbers, and all input values must be selected from these sets. You can't modify the definitions of the sets, but you can easily work with them to ensure your calculations are precise and valid. Here are the three key sets you will work with:

  • Set of all real numbers:
  • $$\{x\in\mathbb{R}\}$$ This set includes all real numbers, providing the broadest scope for your computations.

  • Set of non-negative real numbers:
  • $$\{x\in\mathbb{R}\mid x\geq0\}$$ This set includes all real numbers that are greater than or equal to zero, ensuring you're working within non-negative values.

  • Set of positive real numbers:
  • $$\{x\in\mathbb{R}\mid x>0\}$$ This set includes all real numbers that are greater than zero, so only positive values are permitted in your calculations.

    If a value outside of these predefined sets is entered, you'll be promptly alerted that the value is not valid for that particular set.

    Backward Linking: Connecting Calculations to Fundamental Equations

    Our platform enables seamless backward linking between calculations and the fundamental equations they rely on. Where applicable, calculations are linked to their underlying mathematical principles, ensuring greater transparency and traceability.

  • Clear References:
  • When a calculation is based on a fundamental equation, it is linked to its source, allowing users to verify and understand its foundations.

  • Logical Consistency:
  • Inputs and results are checked against the base equations where relevant, helping to prevent errors and maintain accuracy.

  • Structured Knowledge:
  • Instead of isolated calculations, users benefit from an interconnected system where key dependencies between formulas are explicitly documented.

  • Improved Understanding:
  • By following links to fundamental equations, users gain deeper insights into the logic behind computations and can refine their models accordingly.

    This approach enhances both the reliability and comprehensibility of calculations, making complex problem-solving more intuitive and efficient.

    Hidden Values: Reveal Key Calculations When Needed

    Our platform supports hidden values that can be revealed when necessary. Instead of overwhelming users with complex calculations upfront, key values remain hidden until you choose to view them. This approach keeps the interface clean while providing transparency and control over critical computations whenever needed.

    Requirements: Ensure Correct Input Conditions

    Our platform includes Requirements to help users provide valid input values. Instead of guessing acceptable ranges or conditions, you can quickly access predefined requirements to ensure accuracy. This feature ensures that all inputs meet the necessary conditions, preventing errors and improving calculation reliability.

    Unrounded Result: Get Precise Values When Needed

    Our platform allows you to access unrounded results for more precise calculations. By default, values may be displayed with rounding for readability, but when exact precision is required, a button can reveal the full unrounded result.

  • The full precision value without rounding
  • Scientific notation for extremely large or small numbers
  • Decimal expansion beyond standard rounding
  • This feature ensures you have full control over numerical accuracy, whether for engineering, scientific, or financial applications.

    Equations in LaTeX: View Precise Mathematical Representations

    Our platform allows you to view equations in LaTeX, ensuring clarity and precision in mathematical expressions. Instead of displaying static formulas, a button next to relevant sections can open a modal window, showing:

  • Exact LaTeX code for the equation
  • Rendered mathematical expression for easy interpretation
  • Copy functionality to use the LaTeX code elsewhere
  • This feature helps users verify calculations, document their work, and seamlessly integrate equations into reports or academic papers.

    Search: Fast and Efficient Content Discovery

    Our platform features a search modal that allows users to quickly and easily find relevant content. After clicking the search button, a modal window opens with a search input field where you can enter keywords.

  • Once you submit your query, a list of relevant results appears within the modal.
  • You can browse through the results without leaving the current context.
  • Selecting a result will take you directly to the corresponding page.
  • This system enhances efficiency and user experience by streamlining navigation within the platform.
