fracture 0.2.2 (2025-12-01)

• Remove unnecessary system requirement for C++11. R's default is now C++17.

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 fractures 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 fractures 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().

Miscellaneous

• Added pkgdown site.

fracture 0.1.0 (2020-09-03)

• Initial release.
