1. Roundup Function

  • Purpose: Rounds a number up to the nearest integer or specified number of decimal places.
  • Behavior: Always rounds away from zero, regardless of the decimal value.
  • Example:
    • Roundup(4.2) → 5
    • Roundup(-4.2) → -5
    • Roundup(3.14159, 2) → 3.15 (rounds up to 2 decimal places)

2. Rounddown Function

  • Purpose: Rounds a number down to the nearest integer or specified number of decimal places.
  • Behavior: Always rounds towards zero, regardless of the decimal value.
  • Example:
    • Rounddown(4.8) → 4
    • Rounddown(-4.8) → -4
    • Rounddown(3.14159, 2) → 3.14 (rounds down to 2 decimal places)

3. Modulo Function

  • Purpose: Returns the remainder after dividing one number by another.
  • Behavior: If x is divided by y, the result is the remainder of x / y.
  • Formula: Modulo(x, y) = x - (y * floor(x / y))
  • Example:
    • Modulo(10, 3) → 1 (10 ÷ 3 = 3 remainder 1)
    • Modulo(-10, 3) → -1
    • Modulo(10, -3) → 1

4. Ceiling Function

  • Purpose: Rounds a number up to the nearest integer or specified multiple.
  • Behavior: Similar to Roundup, but focuses on the nearest multiple of a value.
  • Example:
    • Ceiling(4.2) → 5
    • Ceiling(-4.2) → -4
    • Ceiling(4.2, 0.5) → 4.5 (rounds up to the nearest 0.5 multiple)

In this case What is the differenece between roundup/ceiling and rounddown/floor? and in which we have to use these all four?
