String floatStr = "1.234";
float floatValue = (new Float(floatStr)).floatValue();
OR
float floatValue = Float.valueOf(floatStr).floatValue();

Just a remark. Since you say 'important' you also have to put the suggested expression in a try ... catch block to process possible conversion exceptions. Also Float provides some means for testing for the special float numbers like infinity, nan, etc.

Cheers.
