"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, tt A 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
