Perhaps you might benefit from some old (1987 vintage) work of mine
that is useful for input of numeric (floating) values.

"The packages Numeric_IO and Name_IO, together with their children and
support, assist a program to read a user's input.  The packages are
intended to support numerical computation by providing Get and Put
procedures for floating numbers and for vectors and matrices of
floating numbers.

"The procedures ease an end-user's burden in preparing inputs for
computational programs.  The rules for input of floating numbers are
relaxed so that program inputs need not conform to the strict Ada
syntax for floating numbers. Facilities allow input either from files
or interactively. Consistent policies throughout all the services
allow programs to address input errors, to prompt the end-user
interactively or to specify optional default values."
