xcalc 2.0 is a scientific calculator with an elegant design. xcalc supports the input of a math expression and calculates the result according to the precedence of operators. It accepts addition, subtraction, multiplication, division and modulo, logical operations (and, or, not), trigonometric functions (sine, cosine, tangent and the inverses, in radian or degree), exponentiation, natural logarithm, square root, parenthesis, e, pi, and result memory.

xcalc supports scientific notation. If a number is too big or too small, the result will be displayed in scientific notation, with a mantissa part and an exponential part. For example, 0.0000087654321 will be displayed as 8.7654321E-6.

xcalc runs on a number of different platforms supporting J2ME, such as Nokia, Sony Ericsson, and Blackberry. To provide the user a happy input experience, keypad, touch screen, QWERTY inputs are all supported. On QWERTY devices, a shortcut is shown as an 'underscore' of the letter to aid the user to choose the right key.

There are different models to choose. Besides xcalc original, we have xcalc black for the professionals, and xcalc diamond (a special edition) putting on a glamorous coat, and some other flavors as well.
