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.
2. To display symbolic variables in numerical format, just call the double function (or any other numerical casting function like int) on them. For example, syms x; % ... double(x) Note that if your variable is a symbolic expression, using double won't work. In such situation, you could use the vpa function to approximate it:
I want to input fractions such as 15/8 into google sheets and have them converted to decimal values. Al the options I choose from format menu turn this into 15/08/22 or unrelated numbers eg 44660
DECIMAL[(M[,D])] Converts a value to DECIMAL data type. The optional arguments M and D specify the precision (M specifies the total number of digits) and the scale (D specifies the number of digits after the decimal point) of the decimal value. The default precision is two digits after the decimal point. try somethin like:
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 {.
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:
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()) Or you can just use the Fraction.from_float() class method: Fraction.from_float(0.25)
Simplified fraction of 7/8 = 7/8 Simplified fraction of 12/8 = 1 1/2 Simplified fraction of 5/16 = 5/16 Simplified fraction of 342/23 = 14 20/23 Simplified fraction of 129/72 = 1 57/72 Source Code: override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib.
1. Firstly, you should prevent your characters from turning into factors in data.frame() df <- data.frame (a, b, c, stringsAsFactors = F) Then you can wrap a simple sapply/lapply inside your lapply to achieve what you want. sapply(X = df, FUN = function(v) {.
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.
