Qalculate! v5.5.2
Qalculate! v5.5.2 The ultimate desktop calculator. Qalculate! is a multi-purpose cross-platform desktop calculator. It is simple to use but provides power and versatility normally reserved for complicated math packages, as well as useful tools for everyday needs (such as currency conversion and percent calculation). Features include a large library of customizable functions, unit calculations and conversion, physical constants, symbolic calculations (including integrals and equations), arbitrary precision, uncertainty propagation, interval arithmetic, plotting, and a user-friendly interface (GTK, Qt, and CLI). Qalculate! is free software, licensed under the GNU Public License v2 (or later). Features: Math Library • Calculation and parsing: -Basic operations and operators: + - * / mod ^ E () &amp;&amp; || ! < > >= <= != ~ &amp; | << >> xor -Fault-tolerant parsing of strings: log 5 / 2 .5 (3) + (2( 3 +5 = ln(5) / (2.5 * 3) + 2 * (3 + 5) -Expressions may contain any combination of numbers, functions, units, variables, vectors and matrices, and dates -Supports complex and infinite numbers -Propagation of uncertainty -Interval arithmetic -Supports all common number bases, as well as negative and non-integer radices, sexagesimal numbers, time format, and roman numerals -Ability to disable functions, variables, units or unknown variables for less confusion: e.g. when you do not want (a+b)^2 to mean (are+barn)^2 but ("a"+"b")^2 -Customizable implicit multiplication -Matrices and vectors, and related operations (determinants etc.) -Verbose error messages -Arbitrary precision -RPN mode • Result display: -Supports all common number bases, as well as negative and non-integer radices, sexagesimal numbers, time format, and roman numerals -Many customization options: precision, max/min decimals, complex form, multiplication sign, etc. -Exact or approximate: ...
