Name Value Description Create variable Edit variable Value must be either number or empty! Variable name clashes with function name! Variable with same name already exists! Name of constant is not valid: name must start with letter, can contain letters, digits and underscore. System variable cannot be changed! Ratio of any circle\'s circumference to its diameter Unique real number such that the value of the derivative (slope of the tangent line) of the function f(x) = e^x at the point x = 0 is equal to 1 Imaginary unit, defined such that i^2 = −1 Speed of light in vacuum, m·s^-1 The gravitational constant is an empirical physical constant involved in the calculation of the gravitational attraction between objects with mass, m^3·kg^−1·s^−2 Physical constant reflecting the sizes of energy quanta in quantum mechanics, J·s Reduced Planck constant, J·s Not a number Infinity Enter new expression Press to copy Continue Donate You can thank the author of this program by email\n\n se.solovyev@gmail.com\n\n donating money via\n\nhttp://paypal.com\n\n or setting 5 stars in\n\nandroid.market History M History is empty!

No grouping separator Apostrophe (\') Space ( ) Grouping separator Sets grouping separator Layout Cellphone Calculator Sets layout of buttons Haptic feedback Toggles vibration on button click Short Middle Long Haptic feedback duration Duration vibration on button click Functions Trigonometric sine function. Trigonometric cosine function. Trigonometric tangent function. Trigonometric cotangent function. Arcsine - the inverse of sine function. Arccosine - the inverse of cosine function. Arctangent - the inverse of tangent function. Arccotangent - the inverse of cotangent function. Natural logarithm - logarithm the base e. Decadic logarithm - logarithm the base 10. Exponential function. Square root function. Cubic root function. Function that gives absolute value of an argument. Function that gives the sign of an argument: -1 if argument is less than 0, 0 if equals to 0, 1 if more than 0. Equals function - gives 1 if two arguments are equals, 0 otherwise. Lesser-or-equals function - gives 1 if two arguments are equals or first is less than second, 0 otherwise. Greater-or-equals function - gives 1 if two arguments are equals or first is greater than second, 0 otherwise. Not-equals function - gives 1 if two arguments are not equals, 0 otherwise. Lesser function - gives 1 if first argument is less than second, 0 otherwise. Greater function - gives 1 if first argument is greater than second, 0 otherwise. Converts degrees into radians: d - degrees, m - minutes (default = 0), s - seconds (default = 0). Converts degrees from DMS notation to decimal notation: d - degrees, m - minutes (default = 0), s - seconds (default = 0). Converts radians into degrees. Unable to create empty constant! Current result is not valid! Operators Modulo operation finds the remainder of division of \'x\' by \'y\'. Sums functions \'f(i)\', iterating through \'i\' from \'from\' to \'to\'. Gives product of functions \'f(i)\', iterating through \'i\' from \'from\' to \'to\'. Gives derivative of order \'order\' of functions \'f(x)\' by \'x\' variable and calculates at point \'x_point\'. Gives integral of function \'f(x)\' by \'x\' variable. Integrates function \'f(x)\' by \'x\' variable from \'a\' to \'b\'.
