Suppose I have a Java class method, which uses * and + operations. int foo(int a, int b) { ... // some calculations with + and * } How to make sure that no overflow occurs in foo ? I guess I can either use BigDecimal or replace all + and * with "wrappers" like: int sum(int a, int b) { int c = a + b; if (a > 0 && b > 0 && c < 0) throw new MyOverfowException(a, b) return c; } int prod(int a, int b) { int c = a * b; if (a > 0 && b > 0 && c < 0) throw

There seems to be a number of similar conversion errors that don't report which column provoked the trouble. This makes fixing mistakes rather difficult in huge queries. Is there some other way to deal with this? 回答1: As far as i know, No, you can't get the error message to show you in which column is failing. But, if you know what you are

For example I have a text T='blah blah blah blah' I need to compress it for this I am using S=zlib.compress(T) Now what I want is to get the ASCII form of S so that I can decompress this T but in a different program. Thanks, EDIT: I guess I got a method to solve it here is the way: import zlib, base64 text = 'STACK OVERFLOW STACK OVERFLOW STACK OVERFLOW STACK OVERFLOW STACK OVERFLOW STACK OVERFLOW STACK OVERFLOW STACK OVERFLOW STACK OVERFLOW STACK OVERFLOW ' code = base64.b64encode(zlib

The problem comes when the button is on the bottom, the drop-down is hidden since the .accordion-body overflow is set to hidden. You can view jsfiddle here: http://jsfiddle.net/DBQU7/6/ So I did what you would expect, tried to do overflow-y:visible . But then you can see the result here, it doesn't work: (You can maybe also notice that the drop-down is inside the div, which creates a scroll bar inside the div instead of just showing up. http://jsfiddle

So what am I doing wrong? @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } res/menu/main.xml 回答1: According to the Material Design specifications , the overflow menu should display on top of the action bar: A menu is a temporary sheet of paper that always overlaps the app bar, rather than behaving as an extension of the app bar.

I can click on the up and down arrows but it only moves the contents up and down by about a pixel or two. This is occuring in Google Chrome (version 18.0) and Iceweasel 11. 回答1: As it turns out, another CSS style was causing the issue: body{ line-height

It has been working beautifully for quite a while, but today I tried to step it up a notch and increase the problem size (it is a research non-standard FE-solver, if that helps anyone...) Now I get the "stack overflow" error message and naturally the program terminates without giving me anything useful to work with. The program starts with setting up all relevant arrays and matrices, and after that is done it prints a few lines of stats regarding this to a log-file. Even with my new,
