%FLOAT (Convert to Floating Format)

%FLOAT(numeric or character expression)

%FLOAT converts the value of the expression to float format. This built-in function may only be used in expressions.

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

The sign is optional. It can be '+' or '-'. It must precede the numeric data.
The decimal point is optional. It can be either a period or a comma.
The exponent is optional. It can be either 'E' or 'e'. The sign for the exponent is optional. It must precede the numeric part of the exponent.
Blanks are allowed anywhere in the data. For example, ' + 3 , 5 E 9' is a valid parameter.
If invalid numeric data is found, an exception occurs with status code 105.

For more information, see Conversion Operations or Built-in Functions.
