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

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
