This may not be what you want, but I turn the mixed number into a fraction. Say 5 1/2, you multiply the whole number (5) by the denominator for the fraction (2), then add the numerator. So you have 5X2+1. That is the new numerator, it goes over the denominator. This gives you 11/2. To check it divide the numerator by the denominator. 2 into 11 gives you 5 (Rem) 1. 1 is the numerator now and it goes over the denomerator. 5 1/2.
I know it sounds like a lot, but try about ten or so, it becomes 2nd nature. You can make it all into decimal, 5 1/2 becomes 5.5, but now you have to put more numbers into the equation.
This is true. I had a math teacher ask me if he had to cut down a tree so I'd have enough scratch paper.
To get a numerical value for a single result, press the diamond button then the ENTER button. To have all results come out numerically, press MODE F2, scroll down to the Exact/Approx line, right-arrow, select 3:APPROXIMATE, then press ENTER ENTER.
Hello, Your TI81 can only perform numerical calculation: It always give uour numbers. The TI89, a more sophisticated calculator, can of course do numerical calculation, BUT ALSO symbolic ones. You ask it for the derivative of sin(x) and it will give you cos(x). Anyway, if you want a decimal result for you calculation above one of the numbers must have a decimal point (instead of writing 2PI write 2.PI.
The TI 89 can do exact calculations. But if you want approximate results any number in the sequence of operations must have the mark of a decimal. Numbers without decimal marks are considered integers, Integer numbers with a decimal mark are treated as floating point numbers ( meaning decimal).
Well, one solution is to fetch the whole data, including the non-numeric part, and then convert that into a number. Most programming languages strips off the non-numeric part of a string when converting into a number. For example, converting '24Michell' to a number will result into '24'. Consult your programming manual on how to convert a string into a number.
