Currency fixed at currency commit aae7701d009b8ba129ffa987f8b550aad50bcc5b

But now there is a new major version, 4.0.

[Bruce Dubbs]

Changes:

• New matrix syntax (column separated by space or comma, rows separated by semicolon, as in matlab)
• Do not make any difference between a vector and a matrix with a single row, or between a scalar and matrix with a single element
• Support input of functions, units, and variables with underscores omitted in names (e.g. µ0 = µ_0, FermiCoupling = fermi_coupling), with some exceptions
• Option to disable "simplified" percentage calculations (e.g. interpret 100 + 20% as 100 + 0.2 instead of 100 × 120%)
• Option to truncate numbers (instead of round to nearest) in result
• Convert K, Hz, and 1/m to J (and derived units) using conversion factor constants (e.g. 1/(550nm) to eV ≈ 2.25 eV)
• Allow use of M as 10^{6 without unit}
• New ksi unit
• New functions: divisors(), rate(), vertcat(), horzcat()
• New plastic number (ρ) constant, and new "hbar" name for reduced Planck constant, and add second Unicode codepoint for µ-sign in constants
• Allow zero (1st and/or 2nd argument) in comb() and perm(), and return zero if second argument (k) is greater than the first (n)
• Calculate statistical functions (e.g. mode(), min(), max(), percentile()) separately for each column of matrix
• Return the lowest value if there are multiple values with equal frequency in mode()
• Parse text argument as expression if concatenate function name is found in text string, and fix concatenate returning date
• New layout for output of result of matrices and equations (qalc)
• Fix Unicode handling on platforms where char is not signed
• Fix bitrot()
• Fix segfault in multisolve() when initial order of equations is not optimal
• Fix segfault with empty sqrt inside sqrt, e.g. sqrt(1+sqrt())
• Fix incompletely calculated nounit(), e.g. in unit conversion
• Minor bug fixes and feature improvements (see the ChangeLog for more details)
