when did the united states come off the gold standard
Gold standard This was meant to be a temporary measure, with the gold price of the dollar and the official rate of exchanges remaining constant. Revaluing currencies was the main purpose of this plan. No official revaluation or redemption occurred. The dollar subsequently floated. In December 1971, the "Smithsonian Agreement" was reached. In this agreement, the dollar was devalued from $35 per troy ounce of gold to $38. Other countries' currencies appreciated. However, gold convertibility did not resume. In October 1973, the price was raised to $42.22. Once again, the devaluation was insufficient. Within two weeks of the second devaluation the dollar was left to float. The $42.22 par value was made official in September 1973, long after it had been abandoned in practice. In October 1976, the government officially changed the definition of the dollar; references to gold were removed from statutes. From this point, the international monetary system was made of pure fiat money.
Coin Coins may be in circulation with fiat values lower than the value of their component metals, but they are never initially issued with such value, and the shortfall only arises over time due to inflation, as market values for the metal overtake the fiat declared face value of the coin. Examples are the pre-1965 US dime, quarter, half dollar, and dollar (nominally containing slightly less than a tenth, quarter, half, and full ounce of silver, respectively), US nickel, and pre-1982 US penny. As a result of the increase in the value of copper, the United States greatly reduced the amount of copper in each penny. Since mid-1982, United States pennies are made of 97.5% zinc, with the remaining 2.5% being a coating of copper. Extreme differences between fiat values and metal values of coins cause coins to be hoarded or removed from circulation by illicit smelters in order to realise the value of their metal content. This is an example of Gresham's law. The United States Mint, in an attempt to avoid this, implemented new interim rules on December 14, 2006, subject to public comment for 30 days, which criminalized the melting and export of pennies and nickels.[30] Violators can be fined up to $10,000 and/or imprisoned for up to five years.
IEEE 754-1985 The leading 1 bit is omitted since all numbers except zero start with a leading 1; the leading 1 is implicit and doesn't actually need to be stored which gives an extra bit of precision for "free."
ARPANET The original IMPs and TIPs were phased out as the ARPANET was shut down after the introduction of the NSFNet, but some IMPs remained in service as late as July 1990.[52][53]
