Formules

Engineers, scientists, and students often need to perform calculations that are difficult to enter on a calculator. If the calculations involve various formulas, with the need to test various input values, a programming language is appropriate, but source code will never be as intuitive as well-rendered mathematics for designing a formula.

With Formulas create beautifully rendered formulas and evaluate them!
You can use real and boolean expressions.
Formulas can be used in other formulas.
On each document, you can define a set of inputs that are used to populate your formulas with values.
