|
invmod - compute modular inverse of an integer
|
||
|
|

|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
invmod <a> <m>
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The B<invmod> program computes the inverse of I<a>, modulo I<m>, if
|
||
|
|
that inverse exists. 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).
