round method

[sarathy rambha]

Hi,
I see compilation while compiling below program. But since round(float) returns int, I am not sure why it thinks return type is double.

float ddd = 3.5;
int j = Math.round(ddd);


Math1.java:84: possible loss of precision
found : double
required: float
float ddd = 3.5;

The message is talking about the first line of code, not the second. "3.5" is a double, and it gets assigned to a float.

The Math class is not part of the exam by the way. As for the error Ulf is right, its on the first line

For float literals, you need to append a letter f to the number, like this:

float ddd = 3.5f;
