double to float

[Alastor]

I'm trying to convert a double value to a float value using the floatValue() method. When I compile I keep getting the error - Method floatValue(double) not found in class. I've tried adding Import java.lang.Number.* but I get the same error. What am I doing wrong?

Hi.<br>
<br>
I just looked up type casting my java book. Which is what I think you want to do. something like <br>
<br>
floatVal=(float)doubleVal;<br>
<br>
Should do the trick. I remember from practice that sometimes javac doesn't like some casting but give it a go.<br>
<br>
The book i've got is "Java software solutions"-Lewis & Loftus. It's really good but it's on JDK 1.6 there probably is a new edition for 2.0 around.

Just read the legal thing that came when I signed up. Sorry sorry sorry. I am in no way affiliated with the publishers or authors of this book. In fact its a good idea to go into you local college/university/other training institiude witha good library and take some time to read through the guides and take some notes. It's a lot chaper that way and you only get what you need.

Thanks for the info. The type casting was what I needed. I'll check out that book, but I won't tell anyone that you told me about it ;-)
