//! Fast, minimal float-parsing algorithm. //! //! minimal-lexical has a simple, high-level API with a single //! exported function: [`parse_float`]. //! //! [`parse_float`] expects a forward iterator for the integer //! and fraction digits, as well as a parsed exponent as an [`i32`]. //! //! For more examples, please see [simple-example](https://github.com/Alexhuszagh/minimal-lexical/blob/master/examples/simple.rs). //! //! EXAMPLES //! -------- //! //! ``` //! extern crate minimal_lexical; //! //! // Let's say we want to parse "1.2345". //! // First, we need an external parser to extract the integer digits ("1"), //! // the fraction digits ("2345"), and then parse the exponent to a 32-bit //! // integer (0). //! // Warning: //! // -------- //! // Please note that leading zeros must be trimmed from the integer, //! // and trailing zeros must be trimmed from the fraction. This cannot //! // be handled by minimal-lexical, since we accept iterators. //! let integer = b"1"; //! let fraction = b"2345"; //! let float: f64 = minimal_lexical::parse_float(integer.iter(), fraction.iter(), 0); //! println!("float={:?}", float); // 1.235 //! ``` //! //!
