[SOLVED] Converting integer to decimal

[xnowandtheworldx]

I need to convert an integer to decimal..if no one can get it that's fine, i'm sure I can find another way, but any help would be nice...

basically this is what I need.

 

[psuedo]

user inputs a number

 

convert_to_decimal(number)

number is converted to a decimal

return number

[/psuedo]

 

now how would I go about doing this?

 

Thank you for any help guys!

What do you mean?  This?

 

$int = 5;

$new = (float) $int;

 

What are you trying to do?

[xnowandtheworldx]

Ah sorry, basically, I need to convert say...5 to .5 I was actually just coming back to say this haha.

[DarkWater]

Uhh......

 

$newnumber = $_POST['number'] / 10;

 

O_O Simple math...

you need to be more specific. Like, give a before/after number example. I vaguely remember back in school "convert to a decimal" meant for instance, taking 12345 and making it 123.45 is that what you mean?

 

edit: ah responses already posted.

[xnowandtheworldx]

Yes...but if it's 100, 100 / 10 = 10. I need this for percentages, so the number that is submitted is the percent, so for instance, if a user inputs 60 it needs to be .60 for the multiplication. Tell me if i'm not making any since.

[DarkWater]

You need a percentage?  Well 5 is not .5 if you're making percentages.  Please be specific.  Thanks.

 

$newnumber = $_POST['number'] / 100;

 

That's a percentage.  123 would 1.23 which is correct.

you pretty much do math the same way with code as you do with paper.... how would you convert 60 to .6 on paper? 60 / 100.  I'm not trying to be mean, but this isn't a math forum, it's a programming forum...

[DarkWater]

And before you say that there's a math based programming board, that's for real math problems that need to be solved with code, not simple division.

haha QFT

haha of course! Man i'm an idiot...sometimes the simplest things seems so much harder than they are haha. Thank you for your help everyone!

I've never seen someone use QFT on a programming board.  That just made my day. xD

I think he wants a script like this

 

<?php

$someNum = 1234567;

# Cheap hack
$newNum = '.' . $someNum;

echo $newNum;

?>

 

Ahh the joys of PHP not caring about type

[DarkWater]

Not if he's doing percentages...

[discomatt]

Ah, missed that part.

[xnowandtheworldx]

Haha, thanks for all the help guys! I did try the '.' . $number; but it didn't work for me for some reason haha, but once again thanks for everyone that helped! It's greatly appreciated.

 

Edit: Finally got the '.' . $number; working haha! Can't believe the first thing I tried actually works, been stressing over this for about an hour haha! But thanks ONCE againe.
