%UNS (Convert to Unsigned Format)

%UNS(numeric or character expression)

%UNS converts the value of the expression to unsigned format. Any decimal digits are truncated. %UNS can be used to truncate the decimal positions from a float or decimal value allowing it to be used as an array index.

If the parameter is a character expression, the following rules apply:

• The sign is optional. It can only be '+' . It can precede or follow the numeric data.
• The decimal point is optional. It can be either a period or a comma.
• Blanks are allowed anywhere in the data. For example, ' + 3 ' is a valid parameter.
• Floating point data is not allowed. That is, where the numeric value is followed by E and an exponent, for example '1.2E6'.
• If invalid numeric data is found, an exception occurs with status code 105
