Changes for version 0.25 - 2018-05-25

  • ADDITIONS
    • sum(a,b,c,...) sum of a list of numbers.
    • prod(a,b,c,...) product of a list of numbers (using binary splitting).
    • as_rat(n,b) rational string-representation of n in base b
    • bell(n) n-th Bell number (OEIS: A000110)
    • catalan(n) n-th Catalan number (OEIS: A000108)
    • euler(n) n-th Euler number (OEIS: A122045).
    • euler_polynomial(n, x) Euler polynomial (also available as `euler(n, x)`)
    • bernoulli_polynomial(n, x) Bernoulli polynomial (also available as `bernoulli(n, x)`).
    • geometric_sum(n,r) geometric sum: r^0 + r^1 + ... + r^n
    • superfactorial(n) product of first n factorials
    • lnsuperfactorial(n) natural logarithm of superfactorial(n)
    • hyperfactorial(n) product of k^k for k=1..n
    • lnhyperfactorial(n) natural logarithm of hyperfactorial(n)
    • bsearch(n,\&f) binary search from 0 to n (exact match)
    • bsearch(a,b,\&f) binary search from a to b (exact match)
    • bsearch_le(n,\&f) binary search from 0 to n (less than or equal to)
    • bsearch_le(a,b,\&f) binary search from a to b (less than or equal to)
    • bsearch_ge(n,\&f) binary search from 0 to n (greater than or equal to)
    • bsearch_ge(a,b,\&f) binary search from a to b (greater than or equal to)
  • IMPROVEMENTS
    • Extended the `gcd()` and `lcm()` functions to accept an arbitrary number of arguments.
    • Extended the optimizations in `digits(n, b)` and `sumdigits(n, b)` for all values of b <= 62.
    • Extended the allowed value of `b` in `base(n, b)`, `as_int(n, b)`, `as_frac(n, b)` and `new(n, b`) to be between 2 and 62.
    • Extended the `float(x)` function to convert `x` to any floating-point number, either real or complex (in this order).
    • Documentation improvements: added a brief description for each function at the top of the POD file.
  • INCOMPATIBLE CHANGES
    • Renamed the Euler-Mascheroni constant from `euler` to `EulerGamma`.
    • Renamed the Catalan constant from `catalan` to `CatalanG`.
  • OTHER
    • Increased the minimum required version of Perl from 5.14 to 5.16 (for `__SUB__`).
    • Merged all the `AnyNum/*.pm` files into the main `AnyNum.pm` file.
