Editing a Number |

When editing a numerical variable an edit line is displayed in the middle of the edit panel. This edit line serves for entering or changing the value of a number.

The text of a number is entered without spaces. The number can be preceded by a sign, **+ **or **-**. The number mantissa can include up to **15 **numerals and a decimal point or a comma. The mantissa can be followed by an exponent separated by **E **or **e**. The exponent is an integer ranging between **-308 **and **+308**.

A number can be entered in the hexadecimal form by inserting the **$ **(dollar) character in front of the number. Thus e.g. the entry **$1F **corresponds the number **31**. Similarly, by inserting the **% **(the percent character) a number can be entered in the binary form. Thus e.g. the entry **%1001 **corresponds the number **9**.
