Listen Read Device Only Added Installed USA TODAY named Calculator Plus among its "25 Essential Apps", calling it the "handy calculator app that's garnered great user ratings"

I'm Calculator Plus - the perfect calculator for Android. I'm easy to use and beautifully designed to do things better than your phone or handheld calculator ever did.

I'm big, easy to read, and I love saving you time and effort. I remember everything you calculate, and let you review it anytime, making me perfect for shopping, doing homework, balancing checkbooks, or even helping with taxes. And if you need to quit and go do something else, I'll have it all waiting for you when you come back. You'll never need to type the same calculation twice again.

I'm attractive and effective and I make great use of your big, beautiful display:

- I show your calculations in clear, elegant type that's easy to read, with commas just where they should be

- You'll never lose track of where you are in a calculation - I show you exactly what's happening at all times

- I remember everything, so you can take a break, then come back later and pick up where you left off

- You can use backspace anytime to correct a simple mistake, instead of starting over

- Use memory to keep a running total you can actually see

- Swipe memory keys aside if you need more advanced math functions

- My percentage key shows exactly what it did, so you're not left confused

- My intuitive, lovable design makes it simple to do everyday calculations on your phone or tablet

Let Calculator Plus on your phone or tablet finally put that handheld calculator to rest.

Listen Read Device Only Added Installed A customizable calculator widget for your homescreen.

Features Include:

★ Themes, currently 4 to choose from but suggestions are welcome for new ones.

★ Large (4x4) and small (3x3) widget sizes

★ Button to toggle between number and function keys

★ Customizable text colors

★ Edit Mode for advanced input

★ and more

-More Information-

There is an F.A.Q. at the bottom of the settings screen that comes up when placing a widget. If you have a question that is not covered there, use the Contact Support button at the bottom of the F.A.Q. to contact me.

-Edit Mode-

This widget can handle more types of input than there is room to put buttons for. To overcome this, you can tap on the display to go into Edit Mode. From here you can copy/paste text, use your hardware or software keyboard, and input functions that are not included in the widget buttons.

For example, the widget contains a button for tangent but not for arctangent. To use arctangent, you can tap on the display and use your keyboard to type "atan". You can then continue to type in edit mode or click done to return to the widget and finish typing there.

Listen Read Device Only Added Installed A simple calculator, the display of which indicates expressions and gives easy operation for editing.

The calculator PanecalST includes features below:

*Four arithmetic operations, root, percentages, and tax calculations

*Calculations with parentheses

* Memory, M+, M-, MR, MC

*Scroll up/down lines

*Easy editing by using a cursor operation

* Cut, copy, and paste

*Expressions history and answer history

*Configurable grouping separator and decimal point

Four arithmetic operations:

1 + 2 - 3 × 4 ÷ 5 = 0.6

Root:

√( 2 × 2 ) = 2

Percentages:

500 + 20% = 600

500 - 20% = 400

500 × 20% = 100

100 ÷ 500% = 20

Tax calculation:

500 Tax+= 525

525 Tax-= 500

Parentheses:

( 1 + 2 ) × ( 3 + 4 ) = 21

( 1 + 2 ) ( 3 + 4 ) ( 5 + 6 ) = 231

Grouping separator and decimal point:

123,456,789.1 + 0.02 = 123,456,789.12

123.456.789,1 + 0,02 = 123.456.789,12

Listen Read Device Only Added Installed Coupler Directivity Calculator is used to calculate the minimum and maximum values of Reflection Coefficient, VSWR, Return Loss and Mismatch Loss.

The Directivity Error Calculator shows the accuracy of a reflection measurement of unknown impedance. It bases its readings on the directivity of the coupler used for the measurement. It is also a convenient way to convert a reflection coefficient to an equivalent standing wave ratio (SWR), return loss, or mismatch loss.

(This is the version without advertising)

Or Reverse:

Enter a resistor value and find the color code.

If the value is not an standard E-series value the two nearest values are shown.

* 3, 4, 5 and 6 band resistor support *

If the resistor has a standard E-series value then also the E-series (E3, E6,E12, E24, E48, E96, E192) number will be shown.
