Answer : pass me a number and return the text

well, I would then create such a table, much easier to maintain ...

you could also create that as a view ...

create function dbo.GetText(@key decimal(20,4) )
returns varchar(2000)
as
  return ( select case @key 
     when 13.00 THEN 'TRECE'
     when 13.01 THEN 'TRECE PUNTO CERO UNO'
     when 13.02 THEN 'TRECE PUNTO CERO DOS'
     --- etc etc -- 
     else 'unknown' end
 )
