It is possible. First, in /skin1/customer/main/products.tpl, you have to modify

$products[product].descr|truncate:300:"...":true

like this:

{eval var=$products[product].descr|truncate:300:"...":true}

Than, you woud call it in the short description like this:

{$products[product].price|string_format:"%.2f"}

and in full description like this:

{$product.price|string_format:"%.2f"}

In /skin1/customer/main/product.tpl, you would use:

{if $product.fulldescr ne ""}{eval var=$product.fulldescr}{else}{eval var=$product.descr}{/if}

I hope this helps.
