RE: What is the result of expression 5.45 + "3.2"?

The result of the expression depends entirely on the rest of the statement in which it appears. If 5.45 is treated as a flow, then a compiler error is thrown:

float a = 5.45 + "3.2" ;

If 5.45 is converted to a String, then the result is "5.453.2":

String a = 5.45 + "3.2" ;

yes absolutely .
if the receiving type is String, then both teh operands will concatenate and form 5.453.2 as an answer.

but if teh recieving type is a primitive type, then that wud be a error.
