Advanced mathematical functions take numeric arguments and produce numeric results.

- Function:
**EXP***(*`exponent`) Returns

*e*(approximately 2.71828) raised to power`exponent`.

- Function:
**LG10***(*`number`) Takes the base-10 logarithm of

`number`. If`number`is not positive, the result is system-missing.

- Function:
**LN***(*`number`) Takes the base-

*e*logarithm of`number`. If`number`is not positive, the result is system-missing.

- Function:
**LNGAMMA***(*`number`) Yields the base-

*e*logarithm of the complete gamma of`number`. If`number`is a negative integer, the result is system-missing.

- Function:
**SQRT***(*`number`) Takes the square root of

`number`. If`number`is negative, the result is system-missing.
