# Description

The ISLOWER function will check that the expression consists of entirely lower case characters. The function takes the general form:

ISLOWER(expression)
1

The expression can return a result of any type. The ISLOWER() function will then return TRUE (1) if the expression consists of entirely lower case characters. The function will return FALSE (0) if the expression contains any characters, which are not lower case characters.

# International Mode

When the ISLOWER() function is used in International Mode, the properties of each character are determined according to the Unicode Standard.
