Hi guys,
sorry for the silly question (I am a Mathematica dummy). I have integrated 
out an expression, and I do not know how to interpret the term like this:
(-1. g + r)^4)
What throws me off is "1. g" (g is a parameter), what is that dot after one
 and there is also a SPACE after the dot and before "g" symbol. Sometimes I
 get smth. like "1. r" what is that supposed to mean? If r=2, then how to
 interpret the latter? Is it 1.2?? Or? Thanks.
