This calculator can be used as common scientific calculator (sin, cos, log, power, root, memory), but it also includes a molecular weight calculator and the tables with various physical and chemical constants. The calculator contains a list with task history, storing all the recent inputs and results. Scientific calculator displays the numbers rounded to a user-specified number of decimal places.">
