round 0.1.0

# round ![](https://travis-ci.org/mohamedhayibor/round.svg?branch=master)

This crate provides utilities to (round, round_up, round_down) your floats with precision from 1 to 10.

## Usage

In your project's Cargo.toml include the package name and version, like so:
```rust
[dependencies]
round = "0.1.0" // or any latest version on crates.io
```

#### examples
```rust
extern crate round;
use round::{round, round_up, round_down};

fn main() {
    // basic rounding
    let test_n = round(8.9534, 2);  // 8.95
    let test_x = round(8.9536, 3);  // 8.954
    let test_y = round(8.9536, -1); // 8.95

    // rounding up
    let test_j = round_up(8.9534, 2); // 8.96
    let test_k = round_up(8.9536, 3); // 8.954

    // rounding down
    let test_l = round_down(8.9534, 2); // 8.95
    let test_m = round_down(8.9536, 3); // 8.953
}
```

> defaults to 2 decimal rounding (round, round_up, round_down) if your chosen number of decimals (i32) is negative or greater than 10.

## API

> round, roud_up, round_down from 0 to 10 precision

## Raison d'etre

Turns out I am in need of this type of operation almost every day. Hopefully it will save you some time as well.
