Pyramid Calc Files

## Pyramid Calc
I've had no idea for creative name. Very simple calculator without annoying numpad. 
It supports basic arithmetic operations (adding, subtracting, modulo etc.) and some 
functions (sine, cosine etc.). It'll be expanded in the nearest future.
### Supported functions
|Name|Parameters  |Example usage|Description            |
|----|------------|-------------|-----------------------|
|sin |x in radians|sin(17)      |sine                   |
|cos |x in radians|cos(17)      |cosine                 |
|tg  |x in radians|tg(17)       |tangent                |
|ctg |x in radians|ctg(17)      |cotangent              |
|max |a, b        |max(5,17)    |max of two numbers     |
|min |a, b        |min(5,17)    |min of two numbers     |
|lg  |a           |lg(17)       |natural logarithm      |
|log |a           |log(17)      |logarithm with base 10 |
### Usage
Just enter input in infix notation and hit enter. If you want to copy result to clipboard, 
hit Ctrl + Shift + C. You can also exit immediately - just hit Escape key.

### Additional info
Pyramid calc allows nesting functions, so you can calculate sine of sine (sin(sin(17))).
