Is there “0b” or something similar to represent a binary number in Javascript
...gned a number that looks like it's in binary, but is actually being parsed base 10. The parseInt function expects a string as the first arg, so it turns it into "1111" (base 10 representation), then re-parses it as if it were base 2.

Divide a number by 3 without using *, /, +, -, % operators
...3 + a/1000*3 + (..). In binary it's almost the same: 1 / 3 = 0.0101010101 (base 2), which leads to a / 3 = a/4 + a/16 + a/64 + (..). Dividing by 4 is where the bit shift comes from. The last check on num==3 is needed because we've only got integers to work with.

How to convert an array of strings to an array of floats in numpy?
...port numpy as np
a = ["1.1", "2.2", "3.2"]
b = np.asarray(a, dtype=np.float64, order='C')
For Python 2*:
print a, type(a), type(a[0])
print b, type(b), type(b[0])
resulting in:
['1.1', '2.2', '3.2'] <type 'list'> <type 'str'>
[1.1 2.2 3.2] <type 'numpy.ndarray'> <type 'num...
