Algebraic
Precedence
(Order of
Evaluation)
Functions within an expression are evaluated in the following
order of precedence. Functions with the same precedence
are evaluated in order from left to right.
1.
Expressions within parentheses. Nested parentheses are
evaluated from inner to outer.
Prefix functions, such as SIN and LOG.
Postfix functions, such as !
Power function,NTHROOT.
Negation, multiplication, and division.
6. Addition and subtraction.
7. AND and NOT.
OR and XOR.
9. Left argument of | (where).
10. Equals, =.
8.
Fractions The HP 38G can display fractions of the form alb. To set
Fractions mode, select Fractions as the Number Format in
Home Modes (■ [MODES]). Specify the number of decimal
places to use for the denominator. For instance, in Fraction 2
format, 29/1000 becomes 2/69 .
To enter a fraction use the [7] key.
Largest and
Smallest
Numbers
The smallest number the HP 38G can represent is 1 xlO“®®
(1E-499). A smaller result is displayed as zero. The largest
number is 9.99999999999x10®’. A larger result is still
displayed as this number.
