Arrays containing floating points

I have tried both of those methods. Here is the code copied directly from the IDE.
sa:Float[] = [0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0]
sb#[] = [0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0]

I comment out sb# and use only sa:Float[] it nets this compile error
Expecting expression but encountered '='
