Calculation Priority Sequence; Type A Functions; Type B Functions - Casio FX-CG20 AU User Manual

k Calculation Priority Sequence
This calculator employs true algebraic logic to calculate the parts of a formula in the following
order:

1 Type A functions

• Coordinate transformation Pol (
• Functions that include parentheses (such as derivatives, integrations, Σ , etc.)
x x
d / d , d 2 / d 2
Max, Median, Mean, Augment, Mat → List, DotP, CrossP, Angle, UnitV, Norm, P(, Q(, R(,
t(, RndFix, log
• Composite functions*

2 Type B functions

With these functions, the value is entered and then the function key is pressed.
x x x !
2 –1
, , , ° ' ", ENG symbols, angle unit °,
3 Power/root ^(
4 Fractions a b
/
5 Implied multiplication format in front of π , memory name, or variable name.
2 π , 5A, Xmin, F Start, etc.
6 Type C functions
With these functions, the function key is pressed and then the value is entered.
' , ' , log, ln,

–1
tanh , (–), d, h, b, o, Neg, Not, Det, Trn, Dim, Identity, Ref, Rref, Sum, Prod, Cuml,
Percent, ΔList, Abs, Int, Frac, Intg, Arg, Conjg, ReP, ImP
7 Implied multiplication format in front of Type A functions, Type C functions, and parenthesis.
2 ' 3 , A log2, etc.
8 Permutation, combination, complex number operator in polar form
9 Metric conversion commands*
0 × , ÷, Int÷, Rmdr
! +, –
@ Relational operators =, ≠ , >, <, ≥ , ≤
# And (logical operator), and (bitwise operator)
$ Or, Xor (logical operator), or, xor, xnor (bitwise operator)

* You can combine the contents of multiple function memory (fn) locations or graph memory
( Y n, r n, X tn, Y tn, X n) locations into composite functions. Specifying fn1(fn2), for example,
results in the composite function fn1 ° fn2 (see page 5-14). A composite function can consist
of up to five functions.

* Metric conversion commands are supported only when the Metric Conversion add-in application
is installed.
