It often raises exception: RuntimeWarning: overflow encountered in exp I understand that operand cannot be stored in allocated space for a float. But how can I overcome the problem? 回答1: You can use the bigfloat package. It supports arbitrary precision floating point

Is this possible? overflow:visible doesn't work! 回答1: You can do it in alternative way: #box { margin:-50px 0 0; padding:50px 0 0 0; background:url(/images/image.png) no-repeat; } 回答2: Put the background on a larger <div> that contains your <div> . 回答3: It is very possible with CSS3. I stumbled on this post while attempting this myself and discovered I could do it.

It all works fine in Firefox and IE7, but IE8 behaves as if overflow:hidden was present instead of overflow:auto . I tried overflow:scroll , still does not help, IE8 simply truncates the content without showing scrollbars. Changing max-height declaration to height makes overflow work OK, it's the combination of max

The test code below (revised after reading your comments) core dump after 4GB. From the gdb trace, stringstream uses the default std::char_traits where int_type is set to 32bit int, rather than 64bit size_t. Any suggestion to work around? #include <stdint.h> #include <iostream> #include <sstream> #include <math.h> using namespace std ; int main ( int narg , char ** argv ) { string str ; stringstream

In it, each process and subprocess can have an arbitrary number of "conditions", which if true, some conditional action is taken. One of the possible conditional actions is a goto statement, where a plain integer is the label (each condition being numbered starting at 1). I'd like to use this feature to evaluate and run a few tasks in a loop, but you can only goto higher-numbered conditions (Don't ask me why... this seems to ruin most of the utility). I have reason to

In my latest Python 2.7 project I encountered the following: RuntimeWarning: overflow encountered in long_scalars Could someone please elaborate what this means and what I could do to fix that? The code runs through, but I'm not sure if it is a good idea to just ignore the warning. It happens during an append process like: SomeList.append(VeryLongFormula) 回答1: Here's an example which issues the same warning: import numpy as np np.seterr(all='warn') A = np.array([10]) a=A[-1] a**a yields RuntimeWarning: overflow

And since there are no scrollbars, there is really no way to make the div go back to its original state. Is anything I should do in addition to specifying the style to prevent this? For example when you select the L with the mouse (in the fiddle) and after that you press the down arrow key while holding down shift (i.e. expanding the selection). http://jsfiddle.net/PeeHaa/H34mM/ Or another scenario

I know it can be traced back to the SoundPool based on other posts 09-15 09:03:09.190: ERROR/AudioCache(34): Heap size overflow! req size: 1052672, max size: 1048576 回答1: SoundPool is hard code the buffer size as 1M for all loaded file. So you probably will get 'heap size overflow' error when you load too much files into SoundPool. I also have this issue on a game project that will load game sound FX into SoundPool and
