## fracture 0.2.1 (2022-05-21)

### New features

`fracture()`

and `frac_mat()`

no longer return an error when receiving a vector containing `NA`

or `Inf`

values (#14).
`fracture(NA)`

now returns `NA`

.
`fracture(Inf)`

now returns `"Inf/1"`

.

### Bug fixes

- Fixed a bug where
`frac_style()`

would print integers in mixed `fracture`

s as `"1 ⁰/₀"`

instead of `"1"`

(#12).

## fracture 0.2.0 (2021-10-25)

### Breaking changes

- The second argument to
`fracture()`

and `frac_mat()`

is now `...`

, which must be empty. As a result, all arguments besides `x`

must now be named. (#5)
`fracture()`

and `frac_mat()`

now default to a denominator of `1`

when `x`

equals `0`

or `1`

. Previously, these would default to a denominator of `max_denom`

. `max_denom`

is still used as the denominator when `x`

is `0`

or `1`

± ε. (#6)

### New features

`fracture()`

and `frac_mat()`

gain the argument `denom`

, which allows the user to set an explicit denominator used by all fractions. (#5)

### Miscellaneous

- The
`print()`

method for `fracture`

s now puts quotes around mixed fractions to increase legibility. (#7)
- Updated
`testthat`

to 3rd edition. (#5)

## fracture 0.1.3 (2021-05-25)

- Implemented STRICT_R_HEADERS in accordance with RcppCore/Rcpp#1158

## fracture 0.1.2 (2020-09-08)

### Bug fixes

- Fixed bug where certain fractions (e.g.
`frac_mat(1307.36, base_10 = TRUE)`

) would cause an floating point rounding error.
- Reimplemented
`decimal_to_fraction_base_10()`

with `double`

rather than `int`

.
- Added tests to cover all base_10 fractions below 10,000/10,000 (reduced to 100/100 when testing on CRAN) and a random sample of base_10 fractions below 10,000,000/10,000,000.

### Documentation fixes

`frac_mat()`

's `max_denom`

should be less than the *inverse* square root of machine double epsilon.

## fracture 0.1.1

### New features

- Added
`frac_style()`

which formats fractures using Unicode superscripts and subscripts.
- Added
`is.frac_mat()`

which tests if a matrix is formatted like the output of `frac_mat()`

.

### Bug fixes

- Fixed bug where certain fractions (e.g. 16/113) would cause an integer overflow in C++.
- Reimplemented
`decimal_to_fraction_cont()`

with `double`

rather than `int`

.
- Added tests to cover all fractions below 1000/1000 (reduced to 100/100 when testing on CRAN) and a random sample of fractions below 10,000,000/10,000,000.

- Fixed bug with fracture math where only the first element would be returned.
- Added error handling for
`NA`

and infinite inputs to `frac_mat()`

.
