%INT converts the value of the expression to integer. Any decimal
digits are truncated. This built-in function may only be used in expressions.
%INT 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 be '+' or '-'. 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
