Not quite true -- it's for every _scalar_ type which includes reals, as well
as discretes:

Hear what RM95 says:

S�Value For every scalar subtype S:

S�Value denotes a function with the following specification:

function S'Value(Arg : String)
return S'Base

This function returns a value given an image of the value as a String,
ignoring any leading or trailing spaces. See 3.5.
