$floor[]

The $floor[] function returns the greatest integer less than or equal to the given value. It always rounds down to the lower integer.

Syntax

$floor[value]

Parameters

Parameter	Type	Required	Description
value	number	Yes	The number to round down.

Behavior

• For a positive number: removes the decimal part. $floor[3.9] → 3.
• For a negative number: rounds down to the next lower integer (more negative). $floor[-3.1] → -4.
• For an integer: returns the integer itself.

Examples

Positive number:

$floor[3.9]
→ 3

$floor[3.1]
→ 3

Negative number:

$floor[-3.1]
→ -4

$floor[-3.9]
→ -4

Integer:

$floor[5]
→ 5

Comparison floor / ceil / round

Value	$floor[]	$ceil[]	$round[]
3.2	3	4	3
3.5	3	4	4
3.9	3	4	4
-3.2	-4	-3	-3
-3.5	-4	-3	-3*

*The exact behavior of $round[] for values ending in .5 may depend on the implementation.

Notes

• The result is always an integer (as a string).
• Useful for calculations of pagination, levels, or any situation requiring an integer.
