The software can complete coordinate conversion, numerical conversion, scientific computation and so on . It is practical, high precision, Knowledge Computing tool. Can be carried out coordinate conversion, numerical conversion, unit conversion, numerical calculation, expression, and there are complex variables, such as the calculation of the formula. Will gradually increase the coordinate cross zone conversion, the two sets of coordinates conversion, area and direction, GPS settings, and so on . Coordinate transformation can be carried out in Beijing 54, Xi'an 80, China 2000, WGS84, UTM and other coordinate system conversion; can be easily carried out to the latitude,longitude and km network. Numerical conversion can be carried out in the length, area, volume, gravity, density, angle, date, energy, and so on several hundred kinds of unit conversion. The formula can be used in some digital and conventional symbols, Chinese characters function, trigonometric functions, variables, formula formula symbols. Using fuzzy intelligent technology, automatic judgment of the meaning of the statement, fuzzy conversion of all kinds of symbols, to complete the high accuracy of intelligent computing. Available keyboard input, or touch screen with the mouse and click on the button, enter the number and symbols, intelligent output high precision computing results.
