+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBBN_set_bit()\fR sets bit \fBn\fR in \fBa\fR to 1 (\f(CW\*(C`a|=(1<<n)\*(C'\fR). The
+number is expanded if necessary.
+.PP
+\&\fBBN_clear_bit()\fR sets bit \fBn\fR in \fBa\fR to 0 (\f(CW\*(C`a&=~(1<<n)\*(C'\fR). An
+error occurs if \fBa\fR is shorter than \fBn\fR bits.
+.PP
+\&\fBBN_is_bit_set()\fR tests if bit \fBn\fR in \fBa\fR is set.
+.PP
+\&\fBBN_mask_bits()\fR truncates \fBa\fR to an \fBn\fR bit number
+(\f(CW\*(C`a&=~((~0)<<n)\*(C'\fR).  An error occurs if \fBa\fR already is
+shorter than \fBn\fR bits.
+.PP
+\&\fBBN_lshift()\fR shifts \fBa\fR left by \fBn\fR bits and places the result in
+\&\fBr\fR (\f(CW\*(C`r=a*2^n\*(C'\fR). Note that \fBn\fR must be nonnegative. \fBBN_lshift1()\fR shifts
+\&\fBa\fR left by one and places the result in \fBr\fR (\f(CW\*(C`r=2*a\*(C'\fR).
+.PP
+\&\fBBN_rshift()\fR shifts \fBa\fR right by \fBn\fR bits and places the result in
+\&\fBr\fR (\f(CW\*(C`r=a/2^n\*(C'\fR). Note that \fBn\fR must be nonnegative. \fBBN_rshift1()\fR shifts
+\&\fBa\fR right by one and places the result in \fBr\fR (\f(CW\*(C`r=a/2\*(C'\fR).
+.PP
+For the shift functions, \fBr\fR and \fBa\fR may be the same variable.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBBN_is_bit_set()\fR returns 1 if the bit is set, 0 otherwise.
+.PP
+All other functions return 1 for success, 0 on error. The error codes
+can be obtained by \fBERR_get_error\fR\|(3).
