"it Each operation is accurate to ± 1 in the 10th digit.

However,

calculations

involving

multiple

operations will cause the error to accumulate. This

is

also

observed

with

internal

calculations

involving multiple operations such as

3fy,

x!, ]f~, nPr, nCr and the like.

Note that the error may be greater near an

inflection point of a function.

■ Sequence of Operations

Calculations are carried out in the following order:

® Coordinate transformations:Pol(x,i/),Rec(r,6)

@ A-type functions:

These are functions where a value must be entered

before you press a function key.

x^, x^, x \ xl, X,

3ci, 3c2, y

Converting angular values ( DRG^)

® Mathematical power and root: '‘(x*),

® a b/c

etc.

® B-type functions

These are functions where a function key must be

pressed before a value is entered.

log, In, e*, 10*, sin, cos, tan, sin ', cos ',

ton“', sinh, cosh, tonh, sinh“', cosh', tanh', ( —)

(Z) Implied multiplication preceding a B-type function:
