This a formula based on the scientific calculator, the results effectively place a longer period (16); Support rigorous expression input (such as cos (23)* sin (34) and cos (23)* sin (34 with the equivalent sin34 cos23*); support for the four band in a few expressions while the band mixed computing (except for the metric system outside the band is not limited to a few integers, as 12d.3axh, xh I kind of calculation can identify the hexadecimal number identifier); the program also doing fine (as produced by the mouse and keyboard , the window to follow the history of computing View), which is very good.
