Large numbers that are a multiple of 10 raised to an integer power
can be written in a convenient
compact form using **exponential** (or engineering) **notation**. For example,
the number 400000, which is 4x10^5, can be written 4E5.

Stat-Ease allows the use of this notation in various places in the program which require a user-inputted equation. For example, the constraint entry tool accepts exponential notation.

The valid forms of exponential notation are as follows:

Positive Exponents:

Format:{coefficient}E{power of 10}{factor ID}

Example:300C, whereCis a factor, can be written 3E2C in exponential notation.

Negative Exponents:

Format:{coefficient}E-{power of 10}{factor ID}

Example:0.004B, whereBis a factor, can be written 4E-3B in exponential notation.

**Example:** The equation “0.004A + 50000F” can be typed as follows in the program:

Note

Do not use the **+** symbol for positive exponents. That is, type 3E2C rather
than 3E+2C to represent the number 300. The **-** symbol is required for
negative exponents.
