B.3 Literals in Ada
An integer can be expressed in any base from 2 to 16 by prefixing the number by its base. For example, the
number 42 to base 10 can be written as:
2#101010# 4#222# 8#52# 10#42# 16#2A#
Note:
The use of #’s to bracket the number.
In a number the underscore character can be used to improve readability. Usually this will be used to separate a
number into groups of three digits.
1_00 1_234.567_
8
The number 12.34 can be written as:
0.123_4E2 1.234E1
3.141_596
1_000_000
a numeric literal is of the type universal_integer or universal_real, which allows the literal to be
used freely with any appropriate type.
