HP 10S

% 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 *(x’), Wy,
x!, {-. mPr, nCr and the like.
Note that the error may be greater near an
inflection point of a function.
m Sequence of Operations
Calculations are carried out in the following order:
©® Coordinate transformations: Pol(x, y),Rec(1, @)
@ A-type functions:
These are functions where a value must be entered
before you press a function key.
x x? x) xl, om, X, Xr, X2, Y
Converting angular values (DRG>)
® Mathematical power and root: *(x”), Y_

© B-type functions
These are functions where a function key must be
pressed before a value is entered.
