CEILING.MATH Function in Excel

CEILING.MATH Function in Excel rounds a supplied number up (regardless of the significance’s sign), to the nearest multiple of a given number.

Positive values are rounded away from zero(which becomes more positive)
If mode=0 then Negative numbers are rounded towards zero(which becomes less negative)
If mode=any other value then Negative numbers are rounded away from zero

CEILING.MATH( number, [significance],[mode])

number – The Number to be rounded up

significance– Multiple of Significance to which the number has to be rounded to

mode – If [mode] = 0 (or is omitted), negative numbers are rounded towards zero.

If [mode]= any other numeric value, negative numbers are rounded away from zero

Note: the arithmetic sign of the [significance] argument is ignored.

15.25 with significance 1 and -1 will result in 16 irrespective of mode value
Mode value matters when number is negative (highlighted in pink color)
-15.25 with significance 1 and mode 0 will result in -15 (rounded toward zero)
-15.25 with significance -1 and mode non ZERO will result in -16 (rounded away from zero)
CEILING.MATH rounds up regardless of significance sign, which means that there is no difference between -1 and 1 of significance values

Note: #VALUE! Error occurs if the supplied arguments are non-numeric.
