EE Key on a CalculatorDate: 10/25/1999 at 16:02:31 From: David Galczynski Subject: EE key on calculator What does "EE" on the calculator stand for? Date: 10/25/1999 at 17:30:17 From: Doctor Schwa Subject: Re: EE key on calculator It means "times ten to the" ... For example, 3.786 EE 12 means 3.786 * 10^12 or 3,786,000,000,000 What does it abbreviate? I don't know. One of the E's certainly means something about exponents, but I don't know why they use a double E. - Doctor Schwa, The Math Forum http://mathforum.org/dr.math/ Date: 7/19/2000 at 13:29:40 From: Doctor TWE Subject: Re: EE key on calculator My understanding is that the EE abbreviates "engineering exponent," so as to distinguish it from a "normal exponent" (i.e. the [y^x] key.) The "normal exponent" key (labeled either [y^x] or [x^y], depending on the manufacturer) raises the base directly to the exponent. For example: 3 [y^x] 4 = 3^4 = 81 As Dr. Schwa pointed out, the EE key multiplies the first value by 10 raised to the second value. For example: 3 [EE] 4 = 3 * 10^4 = 30,000 Note that a similar notation is used in some computer programming languages, but it uses only one E (it may be capitalized or lower case, depending on the machine and language.) For example: 3e4 = 3 * 10^4 = 30,000 I hope this clears it up. - Doctor TWE, The Math Forum http://mathforum.org/dr.math/ |
