Math Utilities
Info
The Math Utilities is a Library for MetaTrader 5 that this library provides a set of handy functions for working with doubles in metatrader 4/5 (mt4/mt5). It includes:- Comparison of doubles: Functions for comparing doubles with a loose tolerance to account for binary rounding errors.
Usage
This tool is typically used for enhancing chart analysis and decision making.
Platform
This Library works exclusively on MetaTrader 5 (both build 600+ and newer versions).
Setup
Place the downloaded file in MQL5/Libraries folder via File ? Open Data Folder in MetaTrader 5.
How to Install and Use Math Utilities
1. Storage: Place library files in the MQL/Libraries directory to ensure they are accessible to your projects.
2. Implementation: Include the library in your code using the #import directive, ensuring you match the exact function names and parameters.
3. Compilation: Ensure the library is present in the directory before you compile your main EA or script, as the compiler links them during this phase.
4. Management: Keep libraries organized in sub-folders if you manage many custom functions to maintain a clean project structure.
Frequently Asked Questions
Q: What is a library file used for? A: Libraries store reusable code modules, allowing you to centralize common logic used by multiple EAs or indicators.
Q: Is a library executable? A: No, libraries are non-executable files containing functions; they must be imported into an EA, indicator, or script to function.
Q: Can I update a library while the platform is running? A: You should compile your EA or script after updating a library to ensure the latest code changes are integrated.

This library provides a set of handy functions for working with doubles in MetaTrader 4/5 (MT4/MT5).Also recommended: ea to math - similar library with strong performance on MetaTrader 5.
It includes:
- Comparison of doubles: Functions for comparing doubles with a loose tolerance to account for binary rounding errors.
- Rounding of doubles: Rounding utilities to ensure consistent and accurate rounding of double values.
- Miscellaneous functions: Additional tools for working with doubles, such as low-level binary operations and formatting to strings.
The comparison functions are particularly useful when dealing with scenarios where exact comparisons can fail due to floating-point imprecision. For example:
- Comparing doubles reached via different calculations: When two double values are calculated independently and expected to be equal, but minor differences in the 16th decimal place can cause exact comparisons to fail.
- Experts with trailing stop function: In Expert Advisors, when comparing the current price to a trailing stop level, a small difference in the double representation can lead to unexpected behavior.
- Experts with hidden take profit function: Similar to the above, when comparing the current price to a hidden take profit level, floating-point imprecision can cause issues.
- Comparing price levels in a grid strategy: In grid trading strategies, where multiple orders are placed at specific price levels, exact comparisons may not work as expected.
By using the loose comparison functions provided in this library, you can ensure that these scenarios are handled correctly, preventing unexpected results in your trading algorithms.
