Floating DIVs in IE7 vs. IE8, Firefox, Chrome and Safari
Hi folks, I'm a bit stumped on this one. I am referring to this page - http://savitarbernese.com/welcome.aspx. At the moment it looks okay on IE7 but I can't seem to get it to work on other browsers. As it stands now I had to wrap a couple of DIVs within tables to make the background extend behind the full content. I'm guessing this has...
Why is the number 16 converted to float(6.1026988574311E_320) by PHP using Zend_Amf
The Zend_Amf specification states that a Number type returned from flash will map to a float in PHP. Fine. But why does the number 16 get returned as 6.1026988574311E_320 ? PHP version is 5.2.9 running on OS X. I have tried forcing a cast to integer in PHP (the above value gets rounded to 0) and also from Actionscript using int(16) - th...

Using iPhone/Objective C CGFloats: Is 0.1 okay, or should it be 0.1f?
Hi there, When using an iPhone Objective C method that accepts CGFloats, e.g. [UIColor colorWithRed:green:blue:], is it important to append a f to constant arguments to specifiy them explicitly as floats, e.g. should I always type 0.1f rather than 0.1 in such cases? Or does the compiler automatically cast 0.1 (which is a double in gener...

Confusing type conversion - 2 Bytes to Double
I was recently asked to take over a project in which waveform data is sampled from a power converter and sent to an intelligent agent where calculations are done and the appropriate actions are taken based on the results. The following (java)snippet is what the previous coder used to convert the byte array into an array of doubles: ...

Width of float no longer shrinks to fit when contents wrap to multiple lines
Here is a test file. Resize the window to be wide enough to hold all four boxes. Notice the container is no wider than the boxes, as intended. Resize the window to be small enough that the boxes are on more than one line. Notice the container is the full width of the page (this is unintended). Why? Is it possible to prevent this in a ...
Easy pretty printing of floats in python?
I have a list of floats. If I simply print it, it shows up like this: [9.0, 0.052999999999999999, 0.032575399999999997, 0.010892799999999999, 0.055702500000000002, 0.079330300000000006] I could use print "%.2f", but that would require a for loop to traverse the list, which I consider to be ugly. I believe that there must be a better s...
How to use CSS float without hiding parts of a DIV
When CSS float is used on a DIV, other DIVs that are not floated continue to occupy the space of the floated DIV. While I am sure this is intentional, I do not know how to achieve the effect I am looking for. Please consider this example: <html> <div style="width:400px"> <div style="width:150px;float:right;border:thin black solid"> ...

Trying to left float a left curly quote but having some issues.
I'm trying to float a large left curly quote so that the blockquote sits just to the left of it. I'm having a couple of issues though. 1) The text in the p tag continues to wrap around the quote symbol even though I declare clear: right; on the blockquote. I have never understood how floats are supposed to work so can someone offer some...
