Ranges for floats in declarations ?

[jamie]

I've gotten into using ranges for variables in the declaration section so the compiler can pick the smallest size needed for the job, today I decided to do that with a float number and it does not seem to work

For example
Var
MyDegreeAngle :0.0..359.9;

With that i can pick a single in most cases and also helps with debugging code.

Any flack on this ?

The problem with ranges for floats is that the range is efectively infinite, even if he limits are known.

What I do for those cases is to use a record + helper/method: the record contains the upper and lower limits and the helper/method test a float against those limits.

But, of course, that doesn't give you the type-selection you want; you'd still have to declare the type
