:mrdocs:

Rotate the bits in this array right by `numBits` positions.

== Synopsis

Declared in `<bdlc_bitarray.h>`

== Description

Shift the values in this array to the right by the specified `numBits` positions, with the low‐order values "rotating" into the high‐order bits. The behavior is undefined unless `numBits <= length()`. Note that the length of this array remains unchanged.

== Parameters

[cols="1,4"]
