parameter　width　Integer: The width of the bar in characters.

Implementation

def self.format(value, width)
	blocks = width * value
	full_blocks = blocks.floor
	partial_block = ((blocks - full_blocks) * BLOCK.size).floor
	
	if partial_block.zero?
		BLOCK.last * full_blocks
	else
		"#{BLOCK.last * full_blocks}#{BLOCK[partial_block]}"
	end.ljust(width)
end
