Hi -

I want to convert a value (which may or may not) be in exponential format to an actual value - e.g. I want 10,000,000,000 rather than the exponential equivalent.  Can anyone suggest code that will convert the exponential value to an actual value?

Thanks!

Pete

$number = 10e10;
print number_format($number);

Hi marchent - that works - thanks!  

The number could have decimals, so I am using the following formula:
$value = number_format  ($value, 20, '.', '')

My only question is that I am uncertain as to how many decimal places there may be, so I am just using an arbitrarily high number, e.g. 20.  Is there anything that I am overlooking - i.e. is there another way to handle a variable number of decimal places.

If not, that is fine - but I just thought that I would check.  Thanks again!

Pete

yeah, your 20 is for number of decimal places to handle.  I don't know any other way to do this.
