Python’s x % y returns a result with the sign of y instead, and may not be exactly computable for float arguments. For example, fmod(-1e-100, 1e100) is -1e-100, but the result of Python’s -1e-100 % 1e100 is 1e100-1e-100, which cannot be represented exactly as a float, and rounds to the surprising 1e100.

Jun 14, 2024 · On Python 3 the calculation yields 6.75; this is because the / does a true division, not integer division like (by default) on Python 2. On Python 2 1 / 4 gives 0, as the result is rounded down. The integer division can be done on Python 3 too, with // operator, thus to get the 7 as a result, you can execute: 3 + 2 + 1 - 5 + 4 % 2 - 1 // 4 + 6

Jul 8, 2013 · I understand the Modulus operator in terms of the following expression: 7 % 5 This would return 2 due to the fact that 5 goes into 7 once and then gives the 2 that is left over, however my confusion comes when you reverse this statement to read:

Feb 8, 2013 · This is pretty much fundamental to the definition of modulus, and it's wrong in Python, and just about every other programming language. But Python 3 comes to the rescue there. Most people who know about // know that it's how you do "integer division" between integers, but don't realize that it's how you do modulus-compatible division between ...

May 9, 2019 · It is used to calculate the remainder of an integer division, like 5 % 3 which yields 2. It returns the remainder for all numeric operands on the left-hand-side (that is, if the first operands is an integer, fraction, float, Decimal numbers.

Dec 8, 2013 · The % operator in python for strings is used for something called string substitution. String and Unicode objects have one unique built-in operation: the % operator (modulo). This is also known as the string formatting or interpolation operator.

Jan 19, 2011 · What the % in python actually is is a modulus operator where x % y gives the remainder of x / y. In this case, what happened was that 75 / 4 is 18, with a remainder of 3, which is why 100 - 3 = 97. Do not try to multiply the percentages, it's a common mistake.

Nov 3, 2017 · I am creating a program that uses age to determine factors such as annual fees, and to count annual fees i am using the modulus operator (%). For some reason a whole number % 1 is not creating 0. Why is it doing this and how can I fix it? My expected output is the word "year" printing every 12 iterations.

Jan 5, 2022 · Python modulus the same as remainder? 3. Inverse of modulo operator in Python. 0.

Feb 7, 2010 · I've noticed differing implementations of the modulus operator in Python and Java. For example, in Python: >>> print -300 % 800 >>> 500 Whereas in Java: System.out.println(-300 % 800); -300 This caught me off guard, since I thought something as basic as modulus was universally interpreted the same way.
