Qalculate 科学计算!是一个多用途的跨平台桌面计算器。它使用简单,但提供了通常为复杂数学软件包保留的功能和多功能性,以及满足日常需求的有用工具(如货币转换和百分比计算)。功能包括一个大型的可定制函数库、单位计算和转换、物理常数、符号计算(包括积分和方程)、任意精度、不确定性传播、区间算术、绘图和用户友好界面(GTK、Qt和CLI)。

修复setbits()中的“位宽”和“有符号整数”参数 - Fix a^(f(x))=a^(b*g(x)) where b=2 or b=3固定a^(f(x))=a^(B*g(x)),其中B=2或B=3
- Fix auto/dual approximation with "where" expression
修复带有“where”表达式的自动/双重逼近 - Fix "where" expressions with multiple inequality statements for a single variable, e.g. "where x>0 and x<10"
修复“where”表达式中包含单个变量的多个不等式语句,例如“where x 0 and x 10” - Fix crash when a variable name/symbol with more than 20 characters is used in "where" expression
修复当在“where”表达式中使用超过20个字符的变量名称/符号时崩溃的问题 - Fix qalc not exiting after factorization in non-interactive mode (CLI)
修复在非交互模式(CLI)下进行因式分解后qalc不退出的问题 - Option to change the max number of history lines saved (GTK, Qt)
选项更改保存的历史记录行数的最大值(GTK,Qt) - Fix subsequent tab completions after completion of unit with prefix (GTK, Qt)
修复在完成带有前缀(GTK,Qt)的单元后的后续选项卡完成 - Save date and time for history items, add search by date, and show date of selected history item in search by date context menu item (GTK)
保存历史项目的日期和时间,添加按日期搜索,并在按日期搜索上下文菜单项中显示选定历史项目的日期(GTK) - Option to save history to separate file (GTK)

修复第二次打开时的空窗口(GTK) - Option (enabled by default) to show expression status (parsed expression and calculated value) as you type in history list, instead of in tooltip (Qt)
选项(默认启用)显示表达式状态(解析表达式和计算值),因为你在历史列表中键入,而不是在工具提示(Qt) - Option to hide toolbar (Qt)隐藏工具栏选项(Qt)
- Option to preserve height of history list when keypad or number bases are shown/hidden (Qt)
