[groovy-dev] Floating point literals

Hi,

Why do we require a digit before the decimal point in floating point 
literals?

foo.groovy: 1: expecting EOF, found '+' @ line 1, column 11.
   println 5 + .3
             ^

1 error

Best,
Martin

Because .3 is ugly? :-)

Because it is the right thing to do?

Writing .3 instead of 0.3 is generally considered a bad thing to do
since it hinders readability.
