//! A `no_std` compatible library for formatting floating point numbers with [`ufmt`](https://crates.io/crates/ufmt).
//!
//! Formatting a float is now as easy as wrapping it in either the [`Uf32`] or [`Uf64`] struct with the number of decimal places to format to.
//!
//! ```rust
//! use ufloat::{Uf32, Uf64};
//!
//! // Format to 3 decimal places.
//! let a = Uf32(123.456, 3);
//! // Format to 5 decimal places.
//! let b = Uf64(123.45678, 5);
//! ```
//!
//! The [`libm`](https://crates.io/crates/libm) crate is used for math operations.

            let bytes = s.as_bytes();
            let remaining_space = self.buffer.len().saturating_sub(self.position);

            if bytes.len() > remaining_space {
                panic!("Please increase test buffer size");
            }

            self.buffer[self.position..self.position + bytes.len()].copy_from_slice(bytes);
