Scientific Calculator

This is a powerful Scientific Calculator
You can use it like a normal calculator, or you can type formulas like (3+7^2)*2
It has many functions you can type in (see below)

numbers/images/decimal.js,numbers/images/calc.js

Examples

Type in 12+2*3 (=18)
Select "deg", type in cos(45) (=0.7071067811865476)
Type in 2/sqrt(2) (=1.414213562373095)

Function Reference

A function will return NaN (Not a Number) when you give it invalid entries, such as sqrt(−1)
