## Function Expressions

List of mathematical functions, which can be used in function textfields:
 Code Mathematical function abs(double) absolute value acos(double) arc cosine asin(double) arc sine atan(double) arc tangent acot(double) arc cotangent ceil(double) Returns the smallest double value that is not less than the argument and is equal to a mathematical integer. cos(double) cosine exp(double) e raised by the power of double floor(double) Returns the largest double value that is not greater than the argument and is equal to a mathematical integer. log(double) natural logarithm (base e) round(double) Returns double with value of closest integer to the argument. sin(double) sine sqrt(double) square root tan(double) tangent cot(double) cotangent sinh(double) hyperbolic sine cosh(double) hyperbolic cosine tanh(double) hyperbolic tangent coth(double) hyperbolic cotangent asinh(double) hyperbolic arc sine acosh(double) hyperbolic arc cosine atanh(double) hyperbolic arc tangent acoth(double) hyperbolic arc cotangent sign(double) Returns 1.0 for positive arguments, -1.0 for negative arguments and 0.0 for argument zero.
