php limit float character

look at the codes plz

$a = '29';
$b = '7';

$c = $a/$b;

echo $c;

PHP:

very simple thing. we divided $a with $b (29 divided by 7)

it will show the result : 4.1428571428571428571428571428571

very long...isnt it?

well i want it to show just 4.14
that means only two number after the point (.)

how can i do this...plz help me

 

try this

$c = number_format($c, 2, '.', '');

 

number_format will only give you 4.1428571428571428571428571428571.
its not going to make it 4.14.

try number_format and the substr to get what you need.

Good luck.

btw

$a = '29';
$b = '7';

$a and $b are strings not integers.

you cant divide 2 strings.(lol/haha=)

you need

$a = 29;
$b = 7;

 

number_format should work fine because I am using it.
If you have problem, you can try to round($c*100)/100

 

tnx niil...that works fine

@astrazone: i didnt need to use substr...only number_format works fine. did u try only number_format urself? im confussed if it depends on php version !!
btw...strings or integers...whatever...both works fine in php 5.2.9

 

Sorry I didnt know that anyway you should do it.
bad habit if you will use any other language you will get into so much trouble trust me.

I dont think that it depends on the php version.
