Which are the number formatting functions?*3 pointsround()replace()floor()pow()index()sort()

The number formatting functions are:

1. round(): This function is used to round a number to the nearest integer or to the specified number of decimals.

2. floor(): This function is used to round a number down to the nearest integer.

3. pow(): This function is not specifically a number formatting function, but it is used to raise a number to the power of another number.

replace(), index(), and sort() are not number formatting functions. They are used for different purposes in programming. For example, replace() is used to replace a specific part of a string, index() is used to find the index of a specific element in a list or string, and sort() is used to sort elements in a certain order.
