Great calculator for programmers

I use this calculator frequently for my job. Easily lets you perform all logical and math operations on any size integer value. Result can be viewed in decimal, binary and hexadecimal at the same time. Works with signed and unsigned values.

The perfect app when you have to quickly test the results from low level bit operations. When I'm testing the values stored in my company's driver registers this app is a huge time saver.

Look, it works, okay?

My goodness, I’ve used it maybe ten times so far in two days, and it asks me for a review every time. I’m just writing this to shut it up, gosh dang, wow.
