### 8. Passing two ints (hours and minutes and converting them to proper decimals) ?    coderanch.com

Start from scratch.....use a pencil/pen and some paper and write out the steps involved in converting hours and minutes into decimals if you were doing it without a computer. From there it should be pretty simple to convert the math into a simple program. Once you have some code written, if it isn't working then feel free to post it here ...

### 11. Pleases help - Convert Int to Doubel value without exponents and decimal value.    java-forums.org

Like I said, the value of the double and the way it is displayed are two completely different things. That scientific notation is not a part of the actual value, it's simply how it's being displayed. So of course the DecimalFormat class methods won't return a double, because the value alone has nothing to do with the format of the output. ...

### 13. Separate the int and decimal parts of a double var    forums.oracle.com

What was the point of posting this. 'double' is a primitive and has no accessible methods. If you actually meant Double then you will find the toString() method does not help since behind the scenes it uses exactly the same approach to converting to a String as is used in converting 'double' to a String.

### 14. I've never heard of a decimal integer    forums.oracle.com

An integer is just an integer. There's no distinction between a decimal integer and any other kind, for a given integer variable. When someone says something like "decimal integer", they probably mean "an integer, formatted as a decimal (base 10) number." It's not a different type. Using "%i" for integer doesn't mean anything (or at least not much) because the question ...

### 15. Replacing integers after a decimal    forums.oracle.com

Read the file a line at a time and then use a regular expression to detect a number with a decimal point and replace it with the number with the decimal point and following decimal digits removed. P.S. Why do you need to do this in Java? It just takes about 6 lines of perl.

### 17. its not accepting an integer rather it accepts decimal, chars etc...    forums.oracle.com

The NF-parser does not check for the minus sign when parsing. You have to do that check yourself, since it is in the program logic and not in the parsing logic. The generic parser class should not be implemented in such a way that it is possible to tell it to parse only positive integers. The parser (more or less) looks ...
