I wrote
return java.lang.Math.round(someVariable*1.234234);
into eclipse in a function which returns an int but it wanted me to include (int) to make it like this
return (int) java.lang.Math.round
What is this (int) doing?
Thanks
Well if you look at the Docs,
http://docs.oracle.com/javase/7/docs/api/java/lang/Math.html
Math.roundreturns a long when it’s parameter isn’t a float.So you have to cast the long to an int.
