True that we'll never, by definition, know the complete value of pi, but:
http://www.isr.umd.edu/~jasonp/pipage.html
and:

The primary purpose of the Data statement is to give names to constants; 
instead of referring to pi as 3.141592653589793 at every appearance, the
variable Pi can be given that value with a Data statement and used instead
of the longer form of the constant.  This also simplifies modifying the
program, should the value of pi change. -Fortran manual for Xerox Computers
