Percent Sign (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The percent sign (%) is the symbol used to indicate a percentage (that the preceding number is divided by one hundred). Related signs include the permille (per thousand) sign and the permyriad (per ten thousand) sign (also known as a basis point), which indicate that a number is divided by one thousand or ten thousand respectively. Higher proportions use parts-per notation. There is no consensus as to whether or not to include a space between the number and percent sign in English. Many authorities prescribe that there should be a space, whilst others advise against it. The brochure of the International System of Units declares in chapter 5: "a space separates the number and the symbol %."
