The schema is SYSIBM.

The INTEGER function returns an integer representation of a number or character string in the form of an integer constant.

numeric-expression
An expression that returns a value of any built-in numeric data type.

If the argument is a numeric-expression, the result is the same number that would occur if the argument were assigned to a large integer column or variable. If the whole part of the argument is not within the range of integers, an error occurs. The decimal part of the argument is truncated if present.

character-expression
An expression that returns a character string value of length not greater than the maximum length of a character constant. Leading and trailing blanks are eliminated and the resulting string must conform to the rules for forming an SQL integer constant (SQLSTATE 22018). The character string cannot be a long string.

If the argument is a character-expression, the result is the same number that would occur if the corresponding integer constant were assigned to a large integer column or variable.

The result of the function is a large integer. If the argument can be null, the result can be null; if the argument is null, the result is the null value.
