SUMMARY

The ROUNDUP() and ROUNDDOWN() functions, available in Microsoft Excel versions 4.0 and later, are not documented in the "Function Reference" version 4.0. These functions are similar to the CEILING() and FLOOR() functions.

MORE INFORMATION

ROUNDUP()

The Roundup function rounds a number up, away from zero.

Syntax:

   ROUNDUP(number, num_digits)
                



Number is any real number that you want rounded up. Num_digits is the number of digits to which you want to round the number.

ROUNDUP() behaves similarly to the ROUND() function, except that it always rounds a number up based on the following rules:

  • If num_digits is greater than 0, then number is rounded up to the specified number of decimal places.
  • If num_digits is 0 or omitted, then number is rounded up to the nearest integer.
  • If num_digits is less than 0, then number is rounded up to the left of the decimal point.

Examples:

   ROUNDUP(3.2,0) equals 4
   ROUNDUP(76.9,0) equals 77
   ROUNDUP(3.14159, 3) equals 3.142
   ROUNDUP(-3.14159, 1) equals -3.2
   ROUNDUP(31415.926, -2) equals 31500
                



ROUNDDOWN()

Rounds a number down, toward zero.

Syntax:

   ROUNDDOWN(number, num_digits)
                



Number: any real number that you want rounded down. Num_digits: the number of digits to which you want to round number.

ROUNDDOWN() behaves similarly to the ROUND() function, except that it always rounds a number down based on the following rules:

  • If num_digits is greater than 0, then number is rounded down to the specified number of decimal places.
  • If num_digits is 0 or omitted, then number is rounded down to the nearest integer.
  • If num_digits is less than 0, then number is rounded down to the left of the decimal point.

Examples:

   ROUNDDOWN(3.2, 0) equals 3
   ROUNDDOWN(76.9,0) equals 76
   ROUNDDOWN(3.14159, 3) equals 3.141
   ROUNDDOWN(-3.14159, 1) equals -3.1
   ROUNDDOWN(31415.92654, -2) equals 31400
