mCalc is a “floating” scalable calculator combining a standard calculator and functions of Tax calculation and Currency Conversion. With mCalc you can perform calculations "on the fly" over the active application! When you are finished with the calculation, you are back to your application with just one tap. mCalc icon in Command Bar makes mCalc easily accessible. After installation, the mCalc icon will appear in the lower right corner of the screen near to the keyboard sign. This useful function lets you make the calculator accessible from any application! For example, working in Pocket Excel, you can make calculations “on the fly” and, using Copy/Paste functions, insert results from mCalc directly to the table and the other way round. With scaling buttons you can set a convenient size of mCalc on your screen. The results of calculations can be inserted directly into external applications, which support Copy/Paste function. To do it, place the stylus on the calculator’s display and hold it there for some time (tap and hold operation).
