  1. A percentage point or percent point is the unit for the arithmetic difference of two percentages. For example, moving up from 40 percent to 44 percent is an increase of 4 percentage points, but a 10-percent increase in the quantity being measured. In literature, the unit is usually either written out, or abbreviated as pp or p.p. to avoid ambiguity. After the first occurrence, some writers abbreviate by using just "point" or "points".

  2. In finance, specifically in foreign exchange markets, a percentage in point or price interest point is a unit of change in an exchange rate of a currency pair. The major currencies are traditionally priced to four decimal places, and a pip is one unit of the fourth decimal place: for dollar currencies this is to 1/100 of a cent. For the yen, a pip is one unit of the second decimal place, because the yen is much closer in value to one hundredth of other major currencies. In the forward foreign ex

  3. A percentage point or percent point is the unit for the difference between two percentages. For example, an increase of 40% to 44% is a 4 percentage point increase, but a 10 percent increase in the total. Retrieved from " ". Category:

    In mathematics, a percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number (pure number); it has no unit of measurement.

    For example, 45% (read as "forty-five percent") is equal to the fraction 45/100, the ratio 45:55 (or 45:100 when comparing to the total rather than the other portion), or 0.45. Percentages are often used to express a proportionate part of a total. (Similarly, one can also express a number as a fraction of 1000, using the term "per mille" or the symbol "‰".)

    In Ancient Rome, long before the existence of the decimal system, computations were often made in fractions in the multiples of 1/100. For example, Augustus levied a tax of 1/100 on goods sold at auction known as centesima rerum venalium. Computation with these fractions was equivalent to computing percentages. As denominations of money grew in the Middle Ages, computations with a denominator of 100 became increasingly standard, such that from the late 15th century to the early 16th century, it

    The term "percent" is derived from the Latin per centum, meaning "hundred" or "by the hundred". The sign for "percent" evolved by gradual contraction of the Italian term per cento, meaning "for a hundred". The "per" was often abbreviated as "p."—eventually disappeared entirely. The "cento" was contracted to two circles separated by a horizontal line, from which the modern "%" symbol is derived.

    The percent value is computed by multiplying the numeric value of the ratio by 100. For example, to find 50 apples as a percentage of 1250 apples, one first computes the ratio 50/1250 = 0.04, and then multiplies by 100 to obtain 4%. The percent value can also be found by multiplying first instead of later, so in this example, the 50 would be multiplied by 100 to give 5,000, and this result would be divided by 1250 to give 4%. To calculate a percentage of a percentage, convert both percentages to

    Due to inconsistent usage, it is not always clear from the context what a percentage is relative to. When speaking of a "10% rise" or a "10% fall" in a quantity, the usual interpretation is that this is relative to the initial value of that quantity. For example, if an item is initially priced at $200 and the price rises 10% (an increase of $20), the new price will be $220. Note that this final price is 110% of the initial price (100% + 10% = 110%). Some other examples of percent changes: 1. An

    someone please indicate the meaning of the 1st paragraph hypothesis... if population never changed, let's say 100 people. in the 80's 40% was smoking, in the 90's 30%. that's a reduction of 10 people. so, the change of 10 from 100, is 10%... where does the 25% cames from? — Preceding unsigned comment added by (talk) 07:45, 3 December 2011 (UTC) 1. 10 people who quit is 25% of 40 people who smoked. Abolen (talk) 20:01, 3 December 2011 (UTC) 1.1. Still "assuming the same total population in both years" is wrong. That only needs to be true if the 25% should also reflect on the change of the absolute number of people who. A reduction from 40% to 30% is a 25% decrease, no matter how the population changed. The whole reason of using % is to become independent of the absolute numbers. And 30%/40%=0.75=75% and that is always true. Therefore, I will remove the false statement. -- (talk) 12:36, 21 December 2011 (UTC) I disagree with this statement in the article:"St...

    What is the symbol of percentage point? — Preceding unsigned comment added by (talk) 07:51, 8 July 2012 (UTC) 1. It's pp. But is there supposed to be a space before it? — Preceding unsigned comment added by (talk) 22:45, 31 July 2012 (UTC) 1. 1.1. Spacing before units is a typographical issue (and thus off-topic) and opinions vary. (FWIW, I would use a tiny, unbreakable space.) See Space (punctuation). — Preceding unsigned comment added by Hans Meine (talk • contribs) 15:47, 11 February 2013 (UTC) 1. Any source about the symbol being “pp”?

    e.g. going from 1% to 9% is an 8 percentage point increase.[citation needed]Who point the citation needed tag in the opening line? Why? Why would a citation be needed for such an obvious fact? Is someone trying to suggest that they believe the increase is actually 8 percent?--XANIA - ЗAНИAWikipedia talk | Wikibooks talk23:21, 15 December 2014 (UTC)

    The definition:"A percentage point or percent point is the unit for the arithmetic difference of two percentages. For example, moving up from 40% to 44% is a 4 percentage point increase, but is a 10 percent increase in what is being measured." may be interpreted in that way that 44% - 40% = 4% is wrong. This is not true, since 44% is 44/100 and 40% is 40/100. Thus, 44% - 40% = 44/100 – 40/100 = 4/100 = 4%. Another example: I hope that everyone agrees with 50% = 1/2 and 25% = 1/4. Thus 50% - 25% = 1/2 – 1/4 = 2/4 – 1/4 = 1/4. If 25 % = 1/4, then 1/4 = 25%. Explanation: One may argue that percentages indicate ratios, not differences. However, the difference of two ratios is a ratio again. Proof: Let’s consider this: 1. x m − y n = x n − y m m n {\\displaystyle {\\frac {x}{m}}-{\\frac {y}{n}}={\\frac {xn-ym}{mn}}} As one can see, we've got the fraction again. Moreover, in our case (when talking about percentage) m = n = 100 since a percentage (from Latin per centum "by a hundred") is a num...
