Purpose
Return value
Syntax
=FLOOR.PRECISE(number,[significance])- number - The number that should be rounded.
- significance - [optional] Multiple to use when rounding. Default is 1.
How to use
The Excel FLOOR.PRECISE function rounds a number down to a given multiple, where multiple is provided as the significance argument. If the number is already an exact multiple, no rounding occurs and the original number is returned.
The FLOOR.PRECISE function takes two arguments, number and significance. The number argument is the numeric value to round down, and is the only required argument. With no other input, CEILING.PRECISE will round number up to the next integer.
The significance argument is the multiple to which number should be rounded. In most cases, significance is provided as a numeric value, but FLOOR.PRECISE can also understand time entered as text like "0:15". The default value of significance is 1.
Examples
By default, FLOOR.PRECISE rounds down to the next integer, with a significance of 1.
=FLOOR.PRECISE(3.75) // returns 3
=FLOOR.PRECISE(8.9) // returns 8
To round to a different multiple, provide a value for significance :
=FLOOR.PRECISE(5.75,3) // returns 3
=FLOOR.PRECISE(5.75,2) // returns 4
=FLOOR.PRECISE(5.75,0.5) // returns 5.5
Rounding negative numbers
The FLOOR.PRECISE function always rounds negative numbers down away from zero, and ignores the sign of significance.
=FLOOR.PRECISE(-4.1) // returns -5
=FLOOR.PRECISE(-4.1,1) // returns -5
=FLOOR.PRECISE(-4.1,-1) // returns -5
FLOOR.PRECISE vs FLOOR
The FLOOR.PRECISE function differs from the FLOOR function in these ways:
- Provides a default significance of 1, rounding to nearest integer
- Always rounds negative numbers down away from zero
- Ignores the sign of significance (uses the absolute value)
Notes
- FLOOR.PRECISE always rounds negative down away from zero.
- If number is an exact multiple of significance, no rounding occurs.
- To round to the nearest multiple (up or down) see the MROUND function.
Related functions
MROUND Function
The Excel MROUND function returns a number rounded to a given multiple. MROUND will round a number up or down, depending on the nearest multiple.
FLOOR Function
The Excel FLOOR function rounds a given number down to the nearest specified multiple. FLOOR works like the MROUND function, but FLOOR always rounds down.
ROUND Function
The Excel ROUND function returns a number rounded to a given number of digits. The ROUND function can round to the right or left of the decimal point.
ROUNDDOWN Function
The Excel ROUNDDOWN function returns a number rounded down to a given number of places. Unlike standard rounding, where only numbers less than 5 are rounded down, ROUNDDOWN rounds all numbers down....
ROUNDUP Function
The Excel ROUNDUP function returns a number rounded up to a given number of decimal places. Unlike standard rounding, where only numbers less than 5 are rounded down, ROUNDUP rounds all numbers up....
CEILING Function
The Excel CEILING function rounds a given number up to the nearest specified multiple. CEILING works like the MROUND function, but CEILING always rounds up.
EVEN Function
The Excel EVEN function rounds numbers up to the next even integer. The EVEN function always rounds numbers away from zero, so positive numbers become larger and negative numbers become smaller (i.e. more negative).
ODD Function
The Excel ODD function returns the next odd integer after rounding a given number up. The ODD function always rounds numbers away from zero, so positive numbers become larger and negative numbers become smaller (i.e. more negative).
INT Function
The Excel INT function returns the integer part of a decimal number by rounding down to the integer. Note that negative numbers become more negative. For example, while INT(10.8) returns 10, INT(-10.8) returns -11.
TRUNC Function
The Excel TRUNC function returns a truncated number based on an (optional) number of digits. For example, TRUNC(4.9) will return 4, and TRUNC(-3.5) will return -3. The TRUNC function does no rounding, it simply truncates as specified.
