Attribute Universal_Literal_String (GNAT Reference Manual) (original) (raw)

4.70 Attribute Universal_Literal_String ¶

The prefix of Universal_Literal_String must be a named number. The static result is the string consisting of the characters of the number as defined in the original source. This allows the user program to access the actual text of named numbers without intermediate conversions and without the need to enclose the strings in quotes (which would preclude their use as numbers).

For example, the following program prints the first 50 digits of pi:

with Text_IO; use Text_IO; with Ada.Numerics; procedure Pi is begin Put (Ada.Numerics.Pi'Universal_Literal_String); end;
