Uncertainty calculator provides the typical functions of a calculator, extended to operate on numbers with uncertainties (numbers of the form: nominal value ± absolute uncertainty). 

Quickly double-check your answers, or speed up your science/engineering lab work.

Features
•  Result save slots
•  A stylized, live-updating equation preview
•  A "format" option to display the result in the standard uncertainty format
•  Natural equation input (AB for A*B, 1.0E3 for 1000)

This utility supports square root, trigonometric (including inverse and hyperbolic), log (natural and base 10), and exponential functions.

Uncertainty rules
The calculated value of every absolute uncertainty is found through some combination of the following three rules:

1. Absolute uncertainties are combined during addition and subtraction.

2. Percentage uncertainties are combined during division and multiplication.

3. For operations that can't (easily) be converted to comply with the above two, the "brute force" method is used.
