"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

©InTT, e(base of natural logarithm), implied

multiplication involving a memory or variable

name : lit, 3e, 5A, ttA 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:

2VJ, Alog2 etc.

® Permutations and combinations:nPr, nCr

1 2 ... 29 30 31 32 33 34 35 36 37 38 39 ... 43 44
