+# SciCalc
+
+Simple scientific calculator. I needed one, so I wrote a basic one, no design frills. Input expressions are slightly post processed and then evaluated
+by the JS interpreter.
+
+## Usage
+
+Buttons are arranged on 3 separate screens, swiping left or right switches between them. Swiping down has the same effect as hitting the "=" button.
+
+## Features
+
+The calculator supports the following operations:
+
+ * basic arithmetic: +, -, *, /, ^ (raise to a power), +/- (invert sign), 1/x (inverse), use of parentheses
+ * trigonometric fucntions: sin, cos, tan, asin, acos, atan
+ * exponential exp, natural logarithm log, pow function (this one takes 2 comma separated arguments)
+ * Pi is provided as a constant
+ * a memory button "M" stores or recalls the last result (after hitting the "=" button or swiping down)
