  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. Converting a floating-point decimal value to a fraction

    stackoverflow.com/questions/26643695

    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.

  4. 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) {.

  5. So i want to be able to convert any decimal number into fraction. In both forms such as one without remainder like this: 3/5 or with remainder: 3 1/4. what i was doing is this.. lets say i have number .3435. Calculate amount of digits after decimals. multiply by 10 with power of the amount before number. then somehow find greatest common factor.

  6. 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.

  7. Algorithm for simplifying decimal to fractions. I tried writing an algorithm to simplify a decimal to a fraction and realized it wasn't too simple. Write 0.333333... as 1/3 for example. Or 0.1666667, which is 1/6. Surprisingly I looked online and all the code I found was either too long, or wouldn't work in some cases.

  8. However, in mathematics we have 3 situations for converting a decimal number into a fraction, I am not going to explain them because It will take a lot of space and time, I have already written a program for this problem. This is the code : import java.math.BigDecimal; import java.math.BigInteger; public class Main {.

  9. #include <iostream> using namespace std; // converts the string half of the inputed decimal number into numerical values void converting (string decimalNumber, float& numerator, float& denominator ) { float number; string valueAfterPoint = decimalNumber.substr(decimalNumber.find(".") + 1,((decimalNumber.length() -1) )); // store the value after ...

  10. And convert it into its corresponding decimal, to be saved in MySQL, that way I can order by it and do other comparisons to it. But I need to be able to convert the decimal back to a fraction when showing to the user. so basically I need a function that will convert fraction string to decimal: fraction_to_decimal("2 1/4");// return 2.25

  11. Basically: 1st) decide if it's a terminating decimal or not 2nd) If yes, just set the decimal tail / 10^n and reduce the fraction. 3rd) If it doesn't terminate, try to find a repeating pattern including cases where the repetition doesn't start right away.
