This is an amazing JavaScript calculator script that can be used as a common scientific calculator (with functions of sin, cos, log, power, root, memory). However, this JavaScript calculator code also includes a molecular weight scientific calculator and the tables of many physical and chemical constants.Besides, this free JavaScript calculator contains a list of historic tasks, storing all the recent inputs and results. This scientific JavaScript form calculator also displays the numbers rounded to a user-specified number of decimal places automatically in SCI mode. A very advanced and professional online JavaScript calculator but easy to implement.Let's try more HTML JavaScript calculators on jsB@nk: - Chemistry Calculator - Advance calculator with helper - Better Calculator v1.2 - 16 function Scientific Calculator
