FLOOR(number, significance)
- Where 'number' is the numeric value to round and
- significance' is the multiple to round the number.
FLOOR() rounds the number down towards zero, to its nearest multiple of significance.
Description
FLOOR(number, significance)
For Example, FLOOR (3.5, 2) returns 2.
FLOOR (-4.6, -2) returns -4.
- Calci returns an NaN error message if the argument is nonnumeric.
- Calci returns an #ERROR message if 'number' and 'significance' have different signs.
- If the number is an exact multiple of significance, rounding will not be done. Calci will display the same number as output.
- If significance value is not mentioned, Calci assumes it to be 1.
- This function can also be used for array of numbers in form of equation as-
a) FLOOR(3.33..6.33,0.1) where x varies from 3.33 to 6.33 and displays output to multiples of 0.1. Displays 3.3,4.3,5.3,6.3 as output.
b) 2.5..4.5|FLOOR(x+2,2)| where x varies from 2.5 to 4.5 , adds value 2 and displays output to multiples of 2. Displays 4,4,6 as output.
