1//! Fast, minimal float-parsing algorithm.
2//!
3//! minimal-lexical has a simple, high-level API with a single
4//! exported function: [`parse_float`].
5//!
6//! [`parse_float`] expects a forward iterator for the integer
7//! and fraction digits, as well as a parsed exponent as an [`i32`].
8//!
9//! For more examples, please see [simple-example](https://github.com/Alexhuszagh/minimal-lexical/blob/master/examples/simple.rs).
10//!
11//! EXAMPLES
12//! --------
13//!
14//! ```
15//! extern crate minimal_lexical;
16//!
17//! // Let's say we want to parse "1.2345".
18//! // First, we need an external parser to extract the integer digits ("1"),
19//! // the fraction digits ("2345"), and then parse the exponent to a 32-bit
20//! // integer (0).
21//! // Warning:
22//! // --------
23//! //  Please note that leading zeros must be trimmed from the integer,
24//! //  and trailing zeros must be trimmed from the fraction. This cannot
25//! //  be handled by minimal-lexical, since we accept iterators.
26//! let integer = b"1";
27//! let fraction = b"2345";
28//! let float: f64 = minimal_lexical::parse_float(integer.iter(), fraction.iter(), 0);
29//! println!("float={:?}", float);    // 1.235
30//! ```
