thedecimalfraction0.625has value 6/10 + 2/100 + 5/1000, and in the same way thebinaryfraction0.101has value 1/2 + 0/4 + 1/8. These two fractions have identical values, the only real difference being that the first is written in base 10 fractional notation, and the ...

integer is a string of hexadecimal digits representing the whole part of the float number. "." is a dot that separates the whole and fractional parts. fraction is a string of hexadecimal digits representing the fractional part of the float number. "p" allows for adding an exponent value. ex...
>>> 17 / 3 # int / int -> int 5 >>> 17 / 3.0 # int / float -> float 5.666666666666667 >>> 17 // 3.0 # explicit floor division discards the fractional part 5.0 >>> 17 % 3 # the % operator returns the remainder of the division 2 >>> 5 * 3 + 2 # result * divisor +...
The result is the same number expressed in fractional notation. However, this code works as expected only by coincidence. In most cases, you won’t get the intended value due to the representation error that affects float numbers, whether they’re rational or not:...
59. Fractional and Integer Splitter Write a Python program to split the fractional and integer parts of a floating point number. Expected Output : (F) (I) 0/2 = 0.0 (0.0, 0.0) 1/2 = 0.5 (0.5, 0.0) 2/2 = 1.0 (0.0, 1.0) ...
