calculating variable in php not giving correct value

i have a code which fetches value from database and subtracts to give a particular value. the values are coming from the database and there is no problem with that. the code is the following:

    <del>
	<span class="amount">
		<i class="fa fa-inr"></i> 
		<?php echo $getRowVenue['main_price_corporate_artist'];?>
	</span>
</del>
<span>( <b><i class="fa fa-inr"></i> 
<?php
	$strikePrice = $getRowVenue['main_price_corporate_artist'];
	$mainPrice = $getRowVenue['offer_price_corporate_artist'];

	echo $offer_price = $strikePrice - $mainPrice;


?> OFF</b> )
</span>

but when the substraction is done, its not giving me exact value , instead its giving me single digit values like the following: enter image description here

how can i fix this?

Please convert you prices from string with comma to float 

$strikePrice = floatval(str_replace(',','.',$getRowVenue['main_price_corporate_artist']));

$mainPrice = floatval(str_replace(',','.',$getRowVenue['offer_price_corporate_artist']));

It should work

the comma is not a valid character for 'standard' numbers, so PHP converts 13,000 to 13 and 10,000 to 10.

You can use numfmt_parse to use your specific locale number format.
