     10 .SH DESCRIPTION
     11 .B zsqr
     12 calculates the square of an
     13 .IR integer ,
     14 and stores the result in
     15 .IR square .
     16 That is,
     17 .I square
     18 gets
     19 .IR integer ².
     20 .P
     21 It is safe to call
     22 .B zsqr
     23 with non-unique parameters.
     24 .SH RATIONALE
