# ceil function

Applies to: Databricks SQL Databricks Runtime 11.3 LTS and above

Returns the smallest number not smaller than expr rounded up to targetScale digits relative to the decimal point. This function is a synonym of ceiling function.

## Syntax

ceil(expr [, targetScale])

## Arguments

• expr: An expression that evaluates to a numeric.

• targetScale: An optional INTEGER literal greater than -38 specifying by how many digits after the decimal points to round up.

## Returns

If no targetScale is given:

• If expr is DECIMAL(p, s), returns DECIMAL(p - s + 1, 0).

• For all other cases, returns a BIGINT.

If targetScale is specified and expr is a:

• TINYINT

Returns a DECIMAL(p, 0) with p = max(3, -targetScale + 1).

• SMALLINT

Returns a DECIMAL(p, 0) with p = max(5, -targetScale + 1).

• INTEGER

Returns a DECIMAL(p, 0) with p = max(10, -targetScale + 1)).

• BIGINT

Returns a DECIMAL(p, 0) with p = max(20, -targetScale + 1)).

• FLOAT

Returns a DECIMAL(p, s) with p = max(14, -targetScale + 1)) and s = min(7, max(0, targetScale))

• DOUBLE

Returns a DECIMAL(p, s) with p = max(30, -targetScale + 1)) and s = min(15, max(0, targetScale))

• DECIMAL(p_in, s_in)

Returns a DECIMAL(p, s) with p = max(p_in - s_in + 1, -targetScale + 1)) and s = min(s_in, max(0, targetScale))

If targetScale is negative the rounding occurs to -targetScale digits to the left of the decimal point.

The default targetScale is 0, which rounds up to the next bigger integral number.
