question: private static int roundBits ( int bitsRequired ) { int index = Arrays . binarySearch ( SUPPORTED_BITS_PER_VALUE , bitsRequired ) ; if ( index < 0 ) { return SUPPORTED_BITS_PER_VALUE [ - index - 1 ] ; } else { return bitsRequired ; } }
target:  Round a number of bits per value to the next amount of bits per value that is supported by this writer.
