Formula:`GPE = precision / 2`

## Introduction to Greatest Possible Error Calculator

The Greatest Possible Error (GPE) of a measurement is the half of the unit of precision of the measurement. It represents the largest error that can occur due to rounding to a certain precision. In this formula, GPE represents the greatest possible error, measurement is the value being measured, and precision is the smallest division of the measurement scale that is being used. This concept is widely used in fields such as engineering, physics, and mathematics to estimate the maximum uncertainty in measurements.

## Parameter usage:

• `measurement` = value of the measurement
• `precision` = unit of precision of the measurement

## Example valid values:

• `measurement` = 100
• `precision` = 1

## Output:

• `GPE` = greatest possible error of the measurement

## Data validation

Values for both `measurement` and `precision` should be numbers greater than zero to prevent errors.

## Summary

This calculator estimates the maximum error in a measurement based on the precision of the measurement tool.
