Great Calculator! Great calculator, but it has an error it says 0^0=1, by the way is a good tool.

Andrew Petrov

Looks good but... I can't access the sigma(summation) function. Screenshots say it should be next to tangent button, but it's not there. Instead, there's the pi button.

Joe Karlo Seva

Verry good calculator. The best i ever tested Yes, it is. However, how i wish calculus (diferentiation and intigration) and matrics calculation be included in this soft. The latest version state Differential and Integral had been added but both could not be found in the advance keyboards. Please developer please check. Thank you

Gavin Mutch

Great, but missing something What would make this app complete is a way to return the answer in engineering notation. IE answers in scientific notation but to powers of 3. (ans x 10^3n, where n is an integer)

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

FAQ:

* If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc - see en.wikipedia.org/wiki/Kibibyte.

* If you can't find HEX, BIN or OCT modes, go to Menu > Settings and make sure that 'Radix Modes' is checked.

* If the percent key appears to give wrong answers, make sure you are pressing '=' at the end, e.g. '25 + 10 % =' will give 27.5.

* If sin/cos/tan functions don't give the answer you are expecting, make sure you are in the correct angle mode. Degrees, radians and grads are supported, indicated by DEG, RAD, GRAD in the display. Use the DRG key to change mode.

* If any of the digit keys are disabled, or the decimal point doesn't work, or you have answers with letters in, or basic arithmetic appears to be wrong, then you are in binary, octal or hexadecimal mode. Press DEC to return to decimal operation. If you don't need these modes, please make sure that 'Radix Modes' is disabled in the settings.
