The SMALLINT function returns a small integer representation of

Numeric to Smallint

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

The result is the same number that would occur if the argument were assigned to a small integer column or variable. If the whole part of the argument is not within the range of small integers, an error is returned. The fractional part of the argument is truncated.

String to Smallint

string-expression
An expression that returns a value that is a character-string or graphic-string representation of a number.

If the argument is a string-expression, the result is the same number that would result from CAST( string-expression AS SMALLINT). Leading and trailing blanks are eliminated and the resulting string must conform to the rules for forming a floating-point, integer, or decimal constant. If the whole part of the argument is not within the range of small integers, an error is returned. Any fractional part of the argument is truncated.

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

Note

Syntax alternatives: The CAST specification should be used for maximal portability. For more information, see CAST specification.
