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.
```

## Examples

 Function Output FLOOR(55.55,5) 55 FLOOR(1000.34,3) 999 FLOOR(22.3) 22 FLOOR(-143.56,-1) -143
