I created a function that returns a character which is
concatanated with four or five different attributes, but one of them is
float8 that indicates a ratio; but I hava not found a function that
converts a floating point number to a text or char data type. What can I
do with it(Itried to convert it as in the following 'text(int(ratio))' but
it gives the rounded integer value of my ratio as usual...)
