## NerdCalc Description
NerdCalc is a binary, hexadecimal and decimal calculator that displays all three number bases at the same time.  With NerdCalc, you can quickly switch which base you are inputting and the result of your calculations is always updated for all three bases, no matter what the current input mode.   NerdCalc supports both unsigned and 2’s complement, to allow for negative numbers, and can perform basic arithmetic and logic operations as well as bitwise shifting.  Enjoy!

## NerdCalc Reviews in United States

### ***** "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.
-- Mike B V, 2021-11-14

### ***** "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.
-- Astrnmr, 2021-09-21

### ***** "Great for PLC"
Used this today in a training class for a major vehicle manufacturer. Simple and easy to use.

I am needing a tool to convert 2’s complement for MCU coding , I found this tool!

-- mtassinari1, 2016-10-19

### ***** "Excellent calculator!"
Needed a calculator to help me practice subnetting for my Cisco networking classes. This calculator certainly does the trick! Thanks!
-- XxNaHtExX, 2014-03-15

### ***** "Programmer's best friend"
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.
-- Blassphemy123, 2014-02-20

### ***** "Great app"
Really awesome!!
-- Dalilah F., 2013-11-30

### ***-- "Ads = Delete"
Latest "upgrade" includes the ever popular annoying ads "feature".  Deleted and replaced with Pro Calc.
-- IrvingKlaws, 2013-11-21

### ***** "Very handy!"
On a low-level embedded system programming job, this calculator was really useful for converting binary inputs to hex, and general binary math. The background's a bit loud, but the functionality is good!
