Description: 1.这个计算器可用在离散数学的数理逻辑中，纯属工具，随意传播，由java语言实现,解压即可运行，需要按照java环境。可以去这里下载运行环境：http://www.skycn.com/soft/3116.html 2.这个计算器可以计算逻辑表达式的值、对应的真值表、主析取范式、主合取范式。 3.输入表达式时可以在表达式栏中输入，也可用相应的按钮输入，变元只能是PQRST。由于等价连接词无法识别，所以用等号代替，这也是一个无奈的选择。 4.计算前请选择变元个数（默认为3元）并对变元赋值。变元个数最高为5，基本能满足日常的计算。 5.计算器有自动检查表达式是否正确的功能，如果判断功能有误，麻烦您告诉我您的表达式。-1.

Description: 编程：编程实现一个简单的四则运算计算器：从键盘输入一个四则运算表达式(没有空格和括号)，遇等号"="说明输入结束，输出结果。
假设计算器只能进行加减乘除运算，运算数和结果都是整数，4种运算符的优先级相同，按从左到右的顺序计算（即：2+3*5先计算2+3，再计算5*5）。
示例：括号内是说明
-Programming: programming a simple calculator four operations: from the keyboard to enter a four operator expression (no spaces and brackets), the event of an equal sign " =" the instructions to enter the end of output. Calculator can only assume that addition and subtraction multiplication and division operations, the operands and the results are integers, four kinds of operator precedence the same as calculated according to the order from left to right (ie: 2+3* 5 first, a 2+3, and then calculate 5* 5). Example: Figures in bracket shows

Description: 1) 支持基本的四则（+、-、*、/）运算。
2) 支持sin cos tan等三角函数的运算。
3) 支持log、ln、exp、x^y、sqr等复杂的运算。
4) 实现了解析运算（可以输入一个数学表达式，然后正确计算出结果）。
5) 具有清零功能。
6) 具有退格与记忆键。
7) 支持圆周率一键输入。
8) 支持科学计数法输入。
9) 具有连续计算的能力，即上一次计算的结果可以直接参与下一次计算（即兼有标准计算器的特点）。
10) 输入可以通过界面实现，即用鼠标点击按钮；同时支持完全的键盘输入，方便习惯使用键盘的用户。
11) 具有一定得检错能力，能够检测出大部分常见的输入错误（包括键盘输入时的输入错误）。
12) 能够显示当前的日期和时间。

Description: 这是我在大学波尔多1类PROJET。我professieur Mr.Baudon创世这些代码给Java结构hashtree的例子。这是评估一个数值表达式，实现了类计算器。-This is to achieve a class calculator evaluating a numeric expression.
Prefixed expressions are used to facilitate analysis:
no priority
no associativity
the battery is required to calculate the recursive calls
For example,+/4 2 1 the result is 3 (= 4/2+ 1)
On the other hand, the character - being used as a sign by StreamTokenizer, the corresponding binary operator will be represented by the word "less".

Description: 一个通过Java代码实现的科学计算器。
用户可以通过输入一串数学表达式来获得他们想要的结果。功能效果类似于卡西欧计算器，所包含的运算符号包括加(+)、减(-)、乘(*)、除(/)以及次方(^)。
比如输入："( 3 ＋ 5 ) ＊ 2 － 6 ^ 2"，回车后会得到输出结果："-20"。
输入不合法字符会报错，程序健壮度佳。
学习该代码有助于理解科学计算器、卡西欧计算器的运算实现原理。(A class that computes an arithmetic expression.)
