Php calculation question?

[Cagri]

Hello,

 

in PHP when i calculate big numbers,

result is something like that : "1.9753086024691E+15"

i want print all digits not with E+XX

 

i looked at the PHP:BC Math Manual but i didn't understand.

 

how can i fix it?

 

Thanks.

What's not to understand?

 

 

The BCMath functions are extremely straight forward.  You just use them in place of operators like + - * /, and you get a string returned instead of an int or float.

You can also just use sprintf to get it in another formatting. Like

sprintf('%d', $largeInteger);

The value is there, but when you print/echo something, it forces it to a string first. If you use the number_format() function, you will see the whole thing:

<?php
  $num = pow(1234567890,5);
  echo number_format($num);
?>

sprintf('%d', $largeInteger);

 

 

Oh yeah.... I didn't think about sprintf.

 

 

 

Yeah, I didn't think about number_format either.  I'm sure doing the math normally then using number_format is faster than bcpow.

It depends on how large your integers are or how much precision you need on your floats.
