you need to:
* add a real/float/numeric/... wanted column to the table,
* use a function that:
read a row,
get the varchar(20) column,
check for beginning with 0-[1-9],
strip '0-' from the string,
convert it into the wanted format,
update table's real/float/numeric/... column with the result,
loop until end of table.
Reality is for people who can't deal with drugs.
