## Download
[https://github.com/zahash/csc/releases](https://github.com/zahash/csc/releases)
( or )
```
cargo install csc
```
## Usage examples
launch the interactive prompt by typing `csc` to run multiple computations
```sh
a = 10
b = a + 1.14
c = log(b, 3) + sin(PI)
```
or run one off computations by simply providing them
```sh
$ csc 10 + 1.14
$ csc '10 + 1.14 * ln(50)'
```
## Features
```sh
# basic arithmetic and assignment
a = 1
b = -2 % a * (3^2 / 4)
b += 100
# functions
exp(x)
sqrt(x)
cbrt(x)
abs(x)
floor(x)
ceil(x)
round(x)
ln(x)
log2(x)
log10(x)
log(x, b)
sin(rad)
cos(rad)
tan(rad)
sinh(rad)
cosh(rad)
tanh(rad)
asin(rad)
acos(rad)
atan(rad)
asinh(rad)
acosh(rad)
atanh(rad)
```
All calculations are done using [64 bit *binary* floating point arithmetic](https://en.wikipedia.org/wiki/Double-precision_floating-point_format)
(using the Rust type [`f64`](https://doc.rust-lang.org/std/primitive.f64.html)), so you can come across
the limitations of this implementation, and observe behavior that may be different from other “scientific calculators”, such as the following:
* Rounding errors that may be surprising in decimal notation (e.g. evaluating `0.1 + 0.2` prints `0.30000000000000004`).
* Special values such as “infinity”, “not a number” or a negative zero can be the result of calculations that overflow or have invalid arguments.
