take the integer ratio tuple and pass that in as two separate arguments.Īnd a small demo with your sample values: > for f in (0.25, 0.5, 1.25, 3.0):īoth the fractions module and the float.as_integer_ratio() method are new in Python 2.6. Convert decimal numbers to fractions See the steps to arrive at the. Which essentially does the same thing, e.g. Or you can just use the om_float() class method: om_float(0.25) Follow these steps to manually convert any terminating decimal into a fraction: Step 1: Write the decimal number in fraction format, with the number as the. If you are using Python 2.6 still, then Fraction() doesn't yet support passing in a float directly, but you can combine the two techniques above into: Fraction(*0.25.as_integer_ratio()) To convert a decimal to a fraction, take the decimal number and write it as the numerator (top number) over its position value. Decimal to Fraction Calculator Decimal to Fraction Calculator Shows the steps to convert a decimal number to its equivalent fraction. The latter has a very helpful str() conversion: > str(Fraction(0.25))īecause floating point values can be imprecise, you can end up with 'weird' fractions limit the denominator to 'simplify' the fraction somewhat, with Fraction.limit_denominator(): > Fraction(0.185)įraction(3332663724254167, 18014398509481984) To convert a Decimal to a Fraction follow these steps: Step 1: Write down the decimal divided by 1, like this: decimal 1 Step 2: Multiply both top and bottom. save (thefullpath, dynamic variable name goes here) to get the resulting variable name stored in the file. The output of rat is different when there are two outputs than when there is only one. The bar is positioned above the non-repeating part of the decimal. num, dem rat (totalWoman./ totalStudents) The fraction is then num / dem. For instance, let's say you wanted to convert the following to a fraction: 0.321 0708. Step 1: Separate the non-repeating part of the decimal from the repeating part.
DECIMAL INTO A FRACTION CONVERTER HOW TO
Even more, in this article, we will discuss how to convert decimals into fractions manually using a simple formula. So, for that, you can use this converter. But some calculations can be very complex. Use the fractions.Fraction() type: > from fractions import Fraction However, if you want to make life a little easier, use our decimal to fraction conversion calculator instead. Decimal 0.5 Fraction 1/2 What does it mean If we divide 1 by 2 then we get the answer 0.5.
(as of Python 3.6, you can do the same with a decimal.Decimal() object.) Use float.as_integer_ratio(): > (0.25).as_integer_ratio()
