+.SH NAME
+rand, srand \- simple random number generator
+.SH SYNOPSIS
+.LP
+.nf
+\fB/usr/ucb/cc\fR [ \fIflag\fR ... ] \fIfile\fR ...
+
+int \fBrand\fR();

+
+.SH DESCRIPTION
+.sp
+.LP
+\fBrand()\fR uses a multiplicative congruential random number generator with
+period 2^32 to return successive pseudo-random numbers in the range from 0 to
+2^31 \(mi\|1.
+.sp
+.LP
+\fBsrand()\fR can be called at any time to reset the random-number generator to
+a random starting point. The generator is initially seeded with a value of 1.

+.SH NOTES
+.sp
+.LP
+Use of these interfaces should be restricted to only applications written on
+BSD platforms.  Use of these interfaces with any of the system libraries or in
+multi-thread applications is unsupported.
+.sp
+.LP
+The spectral properties of \fBrand()\fR leave a great deal to be desired.
+\fBdrand48\fR(3C) and \fBrandom\fR(3C) provide much better, though more
+elaborate, random-number generators.
+.sp
+.LP
+The low bits of the numbers generated are not very random; use the middle bits.
+In particular the lowest bit alternates between 0 and 1.
