Algebraic precedence order of evaluation Largest and smallest numbers Clearing numbers Using previous results 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. 2. Prefix functions, such as SIN and LOG. 3. Postfix functions, such as ! 4. Power function, ^, NTHROOT. 5. Negation, multiplication, and division. 6. Addition and subtraction. 7. AND and NOT. 8. OR and XOR. 9. Left argument of | (where). 10.Equals, =. The smallest number the hp 39g+ can represent is 1 × 10-499(1E-499). A smaller result is displayed as zero. The largest number is 9.99999999999 × 10499 (1E499). A greater result is displayed as this number. • clears the character under the cursor. When the cursor is positioned after the last character, deletes the character to the left of the cursor, that is, it performs the same as a backspace key. • CANCEL ( ) clears the edit line. • CLEAR clears all input and output in the display, including the display history. The HOME display ( ) shows you four lines of input/output history. An unlimited (except by memory) number of previous lines can be displayed by scrolling.
