[SOLVED] addition of strings

[ziarkaen]

hi all,

 

im trying to add two strings taken from ebay in the format "7.88", "0.23", "3", etc.

using the ordinary '+' operator the result is unpredictably wrong

 

i do not know why this happens, but I have heard of loss of presision when using floating point numbers?!

 

any help would be appreciated

 

examples are:

P=£0.99 | S=£6.99 | T=£.00

P=£0.99 | S=£5.99 | T=£1.00

P=£0.95 | S=£7.95 | T=£2.00

 

where T should be P add S

 

thanks,

Ben

Okay so there are between 0 and 2 numbers after the decimal point? Try this

 

$p=intval($p*100);

$s=intval($s*100);

$t=(($p*$s)/100);
