Calculations
Basic calculation functions:
Negative numbers, exponents,
parenthetical addition/subtraction/
multiplication/division(with priority
sequence judgement function -
true algebraic logic).
Built-in scientific
Trigonometric/inverse trigonometric
functions:
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, π,
random numbers,absolute
values, integers, fractions.
• Statistics: Standard deviation - number of
data, sum, sum of squares,
mean, standard deviation .
Errors may be cumulative with internal continuous
calculations such as x

√y ,x! ,

√x ,sometimes affecting
accuracy .
