%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.
- See Rules for converting character values to numeric values using built-in functions for the rules for character expressions for %DEC.
- Floating point data, for example '1.2E6', is not allowed.
- 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
Figure 1 shows an example of the %UNS built-in function.
