Regex to filter floating points

Consider the following string:

I bought 70 apples for $15.45, 2 cars for 23.000 each

I am in search of a regex that can return the following result:

I bought {NUMBER:70} apples for ${NUMBER:15.45}, {NUMBER:2} cars for 
{NUMBER:23.000} each

I believe the range I would like to filter is a floiting point with (max) 6 digits. I don't know if this would have to be specified.

Any help would be greatly appreciated :)

Try this:

$text = preg_replace("((?<!{NUMBER:)([0-9]+(?:\.[0-9]+)?)(?!}))","{NUMBER:$1}",$text);

This will do what you asked, but also includes a check to ensure that the number hasn't already been put in a {NUMBER:#} container ;)

Without the check:

$text = preg_replace("([0-9]+(?:\.[0-9]+)?)","{NUMBER:$0}",$text);
