资 源 简 介
A simple command line calculator for Unix-like shells.
It supports everything C++ does. In fact, it just creates a C++ program, compiles it, runs it, and deletes it.
Therefore, this calculator requires C++ to be installed.
The command line is:
calc [manipulator] "expression"
Some examples:
```
calc "3+3/4.0"
3.75
calc "3*cos(23)+0x23"
33.4015
calc "M_PI*2"
6.28319
calc hex "2*4<<10"
2000
R=calc "sqrt(pow(3,1/3.0))"
echo $R
1.20094
```
Some notes:
* Put the expression within double quotes ""
* To enter floating point numbers, use the form "x.0" (double precission). See the first expression above.
* When two parameters are used, the first one is the manipulator for output. Some manipulators:
* hex: outputs the result in hexadecimal.
* oct: outputs the result in octal.
