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) {.
12. 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.
A Fraction class is often given as an exercise in beginning OOP programming classes. It's pretty easy to do, and can easily be found by searching for "C# Fraction class" or "Java Fraction class". – Ross Presser
Is there a simple way to convert data in a dataframe from fraction to decimal format? ... Convert Fraction ...
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.
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:
First I will convert the number from the Metric using the Javax.Measure family of functions and I will get a number like 0.3750 Then I will divide the number by ONE_SIXTEENTH which = 0.0625 ONE_SIXTEENTH = 0.0625 The answer 0.3750 / ONE_SIXTEENTH = 6;
def decimal_from_fraction(frac): return frac.numerator / decimal.Decimal(frac.denominator) This is what Fraction.__float__() does (simply divide the numerator by the denominator), but by turning at least one of the two values into a Decimal object you get to control the output. This lets you use the decimal context:
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
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.
