Adds the CEILING function which returns the smallest integer greater than, or equal to, the specified numeric expression.

Changes

• ExpressionFunctions.cs — six overloads covering all supported numeric types: int, bigint, decimal, float, money, real
• FunctionMetadata.cs — autocomplete/IntelliSense entry
• ExpressionFunctionTests.cs — unit tests covering positive, negative, fractional, whole, and null inputs

Usage

SELECT CEILING(4.1)   -- 5
SELECT CEILING(-4.9)  -- -4
SELECT CEILING(5.0)   -- 5
