What This Tool Does

A utility for common mathematical calculations frequently needed in business, finance, data analysis, and everyday applications. It provides comprehensive percentage operations including calculating what percent one value is of another, finding a percentage of a given number, and determining percent increase or decrease between two values for tracking growth or decline metrics. Ratio calculation simplifies proportions between multiple numbers by finding the greatest common divisor and reducing to the smallest whole number representation. Number rounding supports configurable decimal precision from 0 to 10 places for formatting financial figures, measurements, and display values. Random number generation produces both floating-point values with specified decimal precision and integers within defined minimum and maximum bounds for sampling, testing, and simulation purposes. Aggregate functions operate on arrays of numbers to calculate sums, arithmetic averages, and identify minimum and maximum values with their array positions. The greatest common divisor function finds the largest integer that evenly divides all numbers in a set, useful for simplifying fractions and ratio calculations. All operations return formatted strings alongside raw values for immediate display or further computation.

Complex Math Tool - Instructions

Overview

The Complex Math Tool provides a comprehensive set of mathematical operations including percentage calculations, number rounding, random number generation, aggregate operations (sum, average, min, max), ratio simplification, and greatest common divisor computation.

}

Returns: GCD is 12

Common Workflows

Price discount calculation

1. Use math-percentage-of to calculate the discount amount (e.g., 20% of $150)
2. Use math-sum with a negative discount to get the final price

Comparing performance metrics

1. Use math-percent-increase or math-percent-decrease to compare two periods
2. Use math-average to find the mean across multiple data points

Statistical summary of a dataset

1. Use math-sum for the total
2. Use math-average for the mean
3. Use math-min and math-max for the range

Random selection

1. Use math-random-integer for picking random IDs or indices
2. Use math-random-number for generating random decimal values (e.g., test data)

Important Notes

• Division by zero is handled gracefully with descriptive error messages (e.g., percent-calculate with total=0)
• The numbers array order matters for percentage and ratio operations — check each action's description for the expected order
• GCD values are converted to integers before calculation
• Random number generation requires min_value to be strictly less than max_value
• All results include a human-readable formatted or calculation string for easy display
