  • What does the `%` (percent) operator mean? - Stack Overflow
    1 That is the modulo operator, which finds the remainder of division of one number by another So in this case a will be the remainder of b divided by c
  • math - What does the ^ (XOR) operator do? - Stack Overflow
    The XOR ( ^ ) is an logical operator that will return 1 when the bits are different and 0 elsewhere A negative number is stored in binary as two's complement In 2's complement, The leftmost bit position is reserved for the sign of the value (positive or negative) and doesn't contribute towards the value of number
  • Understanding The Modulus Operator - Stack Overflow
    0 Modulus operator gives you the result in 'reduced residue system' For example for mod 5 there are 5 integers counted: 0,1,2,3,4 In fact 19=12=5=-2=-9 (mod 7) The main difference that the answer is given by programming languages by 'reduced residue system'
  • operators - What does := do? - Stack Overflow
    A number of programming languages, most notably Pascal and Ada, use a colon immediately followed by an equals sign (:=) as the assignment operator, to distinguish it from a single equals which is an equality test (C instead used a single equals as assignment, and a double equals as the equality test)
  • math - ` ` vs ` ` for division in Python - Stack Overflow
    In Python 3 x, 5 2 will return 2 5 and 5 2 will return 2 The former is floating point division, and the latter is floor division, sometimes also called integer division In Python 2 2 or later in the 2 x line, there is no difference for integers unless you perform a from __future__ import division, which causes Python 2 x to adopt the 3 x behavior Regardless of the future import, 5 0
  • python - Math operations from string - Stack Overflow
    Let's say I have a standard Python string (such as one obtained from raw_input()), maybe "2 + 2" for simplicity's sake I'd like to convert this string to standard math operations in Python, such
