  2. By using Decimal: from decimal import Decimal. decimals = [0.25, 0.5, 1.25, 3, 0.6, 0.84] for d in decimals: d = Decimal(str(d)) #Cast as string for proper fraction. nominator,denominator = d.as_integer_ratio() if denominator==1: print(a) else:

  3. 2. You can get the fractional part by multiplying the input number by a whole number of hex digits. Then you can use regular integer-to-hex conversion. For example, to get 6 characters after the (hexa)decimal point, multiply the fractional part by 0x1000000. Here is some Java code that will do it. String toHexFraction(double x, int digits) {.

  4. To convert a fraction to a decimal, just divide the top number by the bottom number. 5 divided by 3 would be 5/3 or 1.67. Much like: function decimal(top,bottom) { return (top/bottom) } Hope this helps, haha

    If the input is a string,then you could use Fraction directly on the input: from fractions import Fraction. x='1/2'. x=Fraction(x) #change the type of x from string to Fraction. x=float(x) #change the type of x from Fraction to float. print x.

  6. I want to be able to convert these to decimal before storing them to the database (being able to also convert back would be nice but not necessary). I want to be able to handle both fractions and mixed numbers e.g. 2 1/2 is saved as 2.5

  7. Is there a simple way to convert data in a dataframe from fraction to decimal format? I have a column of data that that's been recorded as a fraction: Levels: 1/2 1/3 ...

  8. Start with 0.1 as your input and follow these steps: Multiply input by 2 (mult column) Take decimal from answer (answer column) as the digit (binary column) Take the fraction (fraction column) as the input for the next step. Repeat steps 1, 2 and 3 until you either get to 0 or a periodic number.

  9. For decimal part, we can employ the general division rule i.e. multiply the remainder with 10 and try dividing again and repeat. Keep record of the remainder we have already come across to prevent the loop from going into unbounded iterations.

  10. Converting a floating-point decimal value to a fraction

    cout_flo2frac(0.333f); } Output. 0.333000004 = 11173626 / 16777216 * 2^(-1) This gives the rational representation of float val = 0.333f; as 5586813/16777216. What remains to be done is determine the convergents of the exact fraction, which can be done using integer calculations, only.

  11. And here is the solution without functions and stored procedures - just for the fun of it. First you have to create new column (I call it decimal) and then fill it with the values converted from the original mixed-format column (called inconsistent) using the following query:
