Calculations
Basic calculation functions:
Negative numbers, exponents, parenthetical addition / subtraction/ multiplication/
division (with priority sequence judgement function -- true algebraic logic)
Built-in scientific function:
trigonometric/inverse trigonometric functions(units of angular measurement:
degrees, radians, grads), hyperbolic/inverse hyperbolic functions, logarithmic/
exponential functions, reciprocals, factorials, square roots, cube roots, powers,
roots, squares, decimal-sexagesimal conversions, binary-octal-hexadecimal
calculations, coordinate transformations
Statistics:
standard deviation – number of data, sum, sum of squares, mean, standard
deviation(two types)
Linear regression – number of data, sum of x, sum of y, sum of squares of x, sum
of squares of y, mean of x, mean of y, standard deviation of x (two types), standard
deviation of y (two types), constant term, regression coefficient, correlation
coefficient, estimated value of x, estimated value of y.
