Dot-separated float constant parsed as table and column identifier

[dymoksc]

Hi, I'm trying to get a column, which has following format: EXP(-1.3 * field_name). 1 is parsed as the name of table for current instance of criteria. The only workaround, that I've found is to represent floats with two integers (original float mulitplied by n divided by n, where n is 10^m and m is equal to decimal places of fraction). Is there any way I can avoid this behavior? Thank you
