Both I<a> and I<m> are arbitrary-precision +integers in decimal notation. The result is written in standard +decimal notation to the standard output. + +If there is no inverse, the message: + + No inverse + +...will be printed to the standard output (an inverse exists if and +only if the greatest common divisor of I<a> and I<m> is 1). + +=head1 SEE ALSO + +gcd(1), isprime(1), lap(1) + +=head1 AUTHOR + + Michael J.
