" If a numeric literal has a decimal point or an exponentiation clause or if 
its magnitude is less than -9223372036854775808 or greater than 
9223372036854775807, then it is a floating point literal."

​Strange: I thought I did something like that, but maybe I did something wrong.
Is quit a while back, so I do not know what I did exactly.

It gives a  float instead of an integer, but that is in my case not a problem.
​
​If it will become a proclem I always can use CAST.

I just changed it to: 2.5E17.
