+# qc
+
+qc is a minimalist desktop calculator app written
+in blazingly fast™ Rust.
+
+![sqrt(2^64) = 4294967296](qc.png)
+
+## Syntax
+
+All of your favorite mathematical operators are supported:
+
+ - `+`: add
+ - `-`: subtract
+ - `*`: multiply
+ - `/`: divide
+ - `//`: computes integer division between two numbers. If the arguments
+   are not both integers, equivalent to `trunc(x/y)`
+ - `%`: modulo
+ - `^`: exponentiation
+
+Adjacent terms are multiplied:
+ - `2pi`
+ - `2log10(100)`
+
+### Functions
+
+There are also a number of numerical functions:
+ - `sqrt`
+ - `log` (or `ln`, `log2` and `log10` also available)
+ - `sin`
+ - `cos`
+ - `tan`
+ - `asin` (or `arcsin`)
+ - `acos` (or `acos`)
+ - `atan` (or `arctan`)
+ - `floor`
+ - `ceil` (or `ceiling`)
+ - `round`
+ - `trunc` (or `truncate`)
+ - `abs`
+
+Parentheses are optional when calling a function:
+
+ - `cos pi` (equivalent to `cos(pi)`)
+ - `cos 2pi` (equivalent to `(cos(2))*pi`)
