The formula is in the usual <a href="http://en.wikipedia.org/wiki/Infix_notation">infix-notation [ext. Link]</a> and has these operators: <code>+</code>, <code>-</code>, <code>*</code>, <code>/</code> and <code>^</code>. Numbers are always decimal, the decimal mark is <code>.</code> and numbers can be prefixed with an <code>-</code> to indicate a negative number. It is a good idea to wrap a negative number in brackets to prevent wrong evaluation (because <code>-</code> is also an operator). Calculations can be grouped with brackets: <code>(</code> and <code>)</code>.</p> <p>Real numbers are supported, complex numbers not.</p> |
