使用说明：

1、该计算器对表达式的要求比较严格

2、该计算器默认采用弧度制，计算角度时则要转换：sin(π/6)=0.5

3、括号必须要匹配

4、注意像And这样的运算，前后数值需要括号：(1011)And(1000)







其他说明：

Backspace ：删除当前输入的最后一位。

CE ：清除当前显示的表达式。

C ：清除当前的计算，开始新的计算。

MC ：清除存储器中的数据。

MR：调用存储器中的数据。

Mod求模(即整数相除求余数)

And按位与， Or按位或， Xor按位异或

dms度分秒切换

Lsh左移， Not按位取反， Int取整数部分

三角函数运算，cos余弦， sin正弦， tan正切

log常用对数, n!阶乘， ln自然对数，

指数运算，F-E科学计数法开关

-Instructions:

1, the calculator more stringent requirements for expression

2, the calculator defaults to radians, the angle will have to calculate the conversion: sin (π/6) = 0.5

3, the brackets must be matched

4, note that operations such as And, need parentheses around the value: (1011) And (1000)







Other notes:

Backspace: Delete the current input of the last one.

CE: Clear the current display of expression.

C: clear the current calculation, start a new calculation.

MC: Clear memory data.

MR: call data in the memory.

Mod Modulus (division remainder is an integer number)

And by bit and, Or by bit or, Xor bitwise XOR

dms degrees minutes and seconds to switch

Lsh left, Not bitwise negation, Int take the integer part

Trigonometric functions, cos cos, sin sine, tan tangent

log common logarithm, n! factorial, ln the natural logarithm,

Exponentiation, F-E switch in scientific notation
