I am pleased to announce the release of Rational 1.5.

Rational is a C++ class implementing rational numbers of limited size with overflow detection. Both numerator and denominator are of type 'int'.

Rational allows you to perform exact calculations and verify at any time if overflow has occurred. Rational does not throw exceptions.

The 'parse' function is intended as a mean of obtaining values exactly representable by small fractions from the command line, for example '0.1', '1/3' or '355/113'.

Rational is used in combination with Arg_parser in GNU ddrescue and GNU Ocrad.

This release is also GPG signed. You can download the signature by appending '.sig' to the URL. If the 'gpg --verify' command fails because you don't have the required public key, then run this command to import it:

  gpg --keyserver --recv-keys 8FE99503132D7742

Changes in version 1.5:

* The option '-s, --sqrt' of the test program now accepts a rational argument.

  * A block of relational tests has been added to the test program.
