Why are floating point numbers inaccurate?
...11001100110011001100110011001100110011001100110 x 1011
Which we can then convert from binary to decimal:
1.1499999999999999 x 23 (inexact!)
And multiply to reveal the final representation of the number we started with (9.2) after being stored as a floating point value:
9.1999999999999993...
Add leading zeroes to number in Java? [duplicate]
...s, then applying it directly to the number. The format for this example is converted as follows:
%% --> %
0 --> 0
%d --> <value of digits>
d --> d
So if digits is equal to 5, the format string becomes %05d which specifies an integer with a width of 5 printing leading zeroes. S...
Returning the product of a list
...her start with a float type list by doing np.prod(np.arange(5.0,101.0)) or convert it to float by doing np.prod(np.array(range(5,101)).astype(np.float64)). Note that NumPy uses np.float64 instead of float. I don't know the difference.

Remove underline from links in TextView - Android
...which is the case for a basic http:// link. However, Linkify is smart and converts a phone number like (212) 555-1212 into the URL tel:2125551212. The new URLSpanNoUnderline call should be passed span.getURL() to retain this info, otherwise you generate bad links that cause exceptions when clicked...
Weird Integer boxing in Java
...ion code is handled by the compiler.
So during compilation phase compiler converts Integer a = 1000, b = 1000; to Integer a = Integer.valueOf(1000), b = Integer.valueOf(1000);.
So it is Integer.valueOf() method which actually gives us the integer objects, and if we look at the source code of Integ...
