App Description

Suppose you want to calculate something quickly: a sales tax amount, a profit, a costs, etc. Just run Expresso, a handy little text editor with calculation capabilities. Type your expression, press Enter, get result and assign it to a variable if you want. Then re-use variables anywhere in text and within new expressions. All expressions are live: change one of them and all dependent expressions are calculated automatically! What could be easier, or more flexible? And besides all features of TextEdit-like editor are always at hand! See demo video: http://is.gd/expresso

Expresso allows you to:

- calculate math expressions inside Rich Text documents;
- assign results to other variables and use those results anywhere in your document or within new expressions;
- annotate calculations with text;
- place expressions anywhere in text;
- organize calculations inside tables like in spreadsheets.

Expresso has common math operators and functions available: (+, -, *, /, %, !, ^) in addition, to the following functions: sum(), count(), min(), max(), median(), stddev(), average(), random(), sqrt(), log(), exp(), ceil(), floor(), sin(), cos(), tan() and others!

Expresso's Simple Features & Rules:

- all dependent expressions are calculated automatically
- press Enter in any place of an expression or just after the last square bracket to calculate a value
- use square brackets [ ] for expressions. For example: [2+2].
- use variables in your expressions. For example: [10*x].
- input the name of a variable before the expression followed by ":". For example: [x:2+2], variable x will have the value 4.
- move the cursor or click on an expression to edit
- calculations can be saved in RTF format or copied to the clipboard.

- ability to calculate expression without using brackets if an expression is on separate line;

You can associate a value with a variable such as [x:10*5] and then use the variable in another expression such as [x/52]. When you calculate the variable "x" all dependent expressions are calculated automatically.
