Enter, Evaluate, and Retrieve Expressions
Enter expressions in QuickCalc using standard mathematical rules of
precedence; review and retrieve computations from the History area; and
understand the rules for using imperial units: length, area, and volume.
QuickCalc evaluates expressions according to the following standard
mathematical rules of precedence:
Expressions in parentheses first, starting with the innermost set
Operators in standard order: exponents first, multiplication and division
second, and addition and subtraction last
Operators of equal precedence from left to right
The Input box of the calculator is where you enter and retrieve expressions.
With QuickCalc, there are two ways you can enter data in the Input box. You
can either enter expressions using the QuickCalc Number Pad buttons, or you
can use the computer keyboard or numeric keypad. To use the computer
numeric keypad, you must have NUMLOCK on.
To evaluate an expression, click the equal (=) sign on the QuickCalc Number
Pad, or press Enter on the computer keyboard.
Understand the Syntax of Expressions
The syntax for QuickCalc expressions and Command prompt calculator
expressions is identical. For example, to perform an operation on the vector
or coordinates 5,2,0, you enter [5,2,0] in the Input box.
You can use the GETVAR function to read the value of a system variable. The
syntax is
getvar(variable_name)
