This is a compact powerful formula calculator which understands most of mathematical functions (trigonometric, hyperbolic, raising to power, extraction of any root,.

), matrix operations, finds roots and minima of functions and calculates integrals. In contrast to majority of calculators it designed as single line on your desktop and 1) occupies minimum of desktop place; 2) lets you type in sequences of operations with many brackets and then calculate the final result (example: 123*(456-78)*sin(1)-exp(0.
