![]() The code below is for the 28S (48X style, but not 100% compatible!), if anyone wants the 42S code just ask for it. You can even specify a default precission. I've implemented it on a 28S and a 42S and it works fine. For other calculators try this little program. Hi! If you've got a 48 or a 32SII no problem: they have that function built in. Message #8 Posted by Xose on, 5:49 a.m., Message #7 Posted by yummy on, 10:23 p.m., That's a lot easier than than going through the menu's too get the "->Q" softkey. Message #6 Posted by Erwin on, 3:53 p.m., If you are using an hp-49g, use the same instructions as for the 48gx, substituting red shift for green shift and 'Q' 'Y^X' for down arrow, Also the 49g requires a switch to RAD mode for some imbecilic reason. Again this returns an approximation fraction. Then press right shift, the green key, and zero to place a right arrow on the input line, then press the large down arrow key, row three column five, to place a 'Q' after the arrow, then press 'ENTER'. If you are using an hp-48gx place a decimal number on the stack and then press the alpha key twice to set alpha entry mode. This will return a near approximation to the stack, i.e. For an hp-48sx place a decimal number on the stack then press left shift, the orange key, and then 'EVAL', '->Q'. If you still need more information on using the to 'Q' function, the following may help. \->Q ? I also like too know this trick, but wat key's must i use? Message #4 Posted by Erwin on, 4:31 a.m., This will return a fraction given a decimal number.6250 = '5/8'. What kind of calculator are you using? If you have a 48 series try using \->Q. If all else fails, go purchase an hp32SII which does the converting for you automatically. This will be the only solution that will give a whole number numerator until you go to another multiple of 8 such as 16. If you get a mixed number for the numerator, then it was not the proper denominator, try again with 3, and so on until you get a whole number (not zero). Start at 2 as the denominator and multiply this with the decimal. If you see a fraction in decimal form and have no idea what the fractional equivalent may be you can try this trial and error algorithim on your calculator. 6250 yields the answer 5 which is the numerator so you have the fraction of 5/8 again. The term a is the numerator and term b is the denominator of the fraction. Drylie on, 10:14 p.m.,Ī fraction a/b is defined by the equation a/b x b = a. Re: Converting a decimal # to a fraction # Message #1 Posted by yummy on, 3:48 p.m. Step 4: Simplify the remaining fraction to a mixed number fraction if possible.ġ.Converting a decimal # to a fraction # The Museum of HP Calculators.Find the Greatest Common Factor (GCF) of the numerator and denominator and divide both numerator and denominator by the GCF. Next, given that you have x decimal places, multiply numerator and denominator by 10 x. First, count how many places are to the right of the decimal. Step 2: Remove the decimal places by multiplication.Step 1: Make a fraction with the decimal number as the numerator (top number) and a 1 as the denominator (bottom number).Apply the negative sign to the fraction answer.Perform the conversion on the positive value.Remove the negative sign from the decimal number.How to Convert a Negative Decimal to a Fraction where the 857142 repeats forever, enter 0.857142 and since the 857142 are the 6 trailing decimal places that repeat, enter 6 for decimal places to repeat. where the 3 repeats forever, enter 1.83 and since the 3 is the only one trailing decimal place that repeats, enter 1 for decimal places to repeat. For a repeating decimal such as 1.8333.where the 36 repeats forever, enter 0.36 and since the 36 are the only two trailing decimal places that repeat, enter 2 for decimal places to repeat. For a repeating decimal such as 0.363636. ![]() where the 6 repeats forever, enter 0.6 and since the 6 is the only one trailing decimal place that repeats, enter 1 for decimal places to repeat. For a repeating decimal such as 0.66666.For repeating decimals enter how many decimal places in your decimal number repeat. This calculator converts a decimal number to a fraction or a decimal number to a mixed number.
