Can php convert these fractions?

[Scooby08]

I was just wondering if php can convert a fraction that I'm getting from an xml feed..

 

The fractions are like so: 4½

 

Otherwise I was thinking of doing a str_replace like so:

 

str_replace('½','.5',$fraction);

 

But that gave me another problem.. It comes out like so:

 

4�.5

 

Any suggestions how I could just get 4.5?

 

Thanks!!

to convert a fraction simply divide the numerator by the denominator n/d:

1/2 would be 1 divided by 2. format it to 2 decimal places.

 

Look at the source and see how the fraction is generated. If its ascii only 1/4,1/2 and 3/4 are available and you would just have to convert the symbol. If there are other fractions then probable just explode it on the slash and divide. if its a graphic and does not have alt description then YOYO.

I would but I don't have control over how the xml is feeding me the fraction..

 

Am receiving them like so: 4½

 

Not like so: 4 1/2

It sounds to me like you will have to match the character code to the appropriate mathematical operation.

[Scooby08]

So how's that done?? preg_match are you meaning??

[teamatomic]

Not talking about having control of the output, just what the raw code is.

<fraction>4 3/4</fraction>
<fraction 4 ¾</fraction>
<fraction>4 &#190;</fraction>

will all display 4 3/4 but are not the same and wont be handled the same, code wise, when you have to work on converting them.

Well I don't have control over that as well.. I didn't make the xml file.. Can't touch it whatsoever..

[teamatomic]

Ah...but obviously you can access it. Look a the raw file, the source. If not how can you expect to work on the file???

[Scooby08]

Yes I can access it.. I guess I'm missing your point.. Could you explain more?

 

How do I convert the symbol??

[teamatomic]

look at the file source and determine what is being used to create the fraction. refer to my earlier post as to the 3 ways to do a fraction in html.

Its a symbol.. How do you suggest I convert?

[teamatomic]

Then just preg_match and convert, easy

¾

¾

The above examples are 3/4, the only ones available are 1/4,/1/2 and 3/4.

 

Look at an ascii table

I did that and then I ran into this problem:

 

4�.5

 

I did happen to get this one to finally work though..

 

preg_replace('/[^A-Za-z0-9]+$/','.5',$string);

 

That one removed all characters that weren't letters or numbers, including that hidden question mark character.. Then it just replaced the ½ at the end.. In my case I will only have ½ if there are fractions, so I can just replace all those with .5..

 

Thanks for helping out on this one teamatomic!! I really appreciate it..
