# Parsing and displaying decimals
## Parsing and displaying
This crate parses strings litterals to decimals, and is flexible regarding \
the input string.
>Primary use should be quick parsing of text for display/presentation where absolute correctness of the rounding operation is not needed, i.e. scraping information from the web, or presenting larger numbers.
## Usage
The crate exposes a Decimal type that implements a trait called #from_text for. The Decimal type is a tuple type that only holds a f64 number.
Decimal also has an implementation for Display.
Example:
```rust
let to_parse = " 789 1 23.2245 \n";
let decimal = Decimal::from_text(to_parse).unwrap();
println!("{}", decimal); // 789 123,22
```
It uses "." as a default seperator. To set a custom one, do this:
```rust
let mut decimal = Decimal::from_text("18292.50").unwrap();
decimal.set_decimal_sign(',');
```
## Todo
- [x] Make decimal seperator and 1000 seperator configurable
- [ ] Round with better precision
- [ ] Change from f64 to BigDecimal for better calculations
