MULTIPLY Function
Returns the value of multiplying the first argument by the second argument. Equivalent to the * operator.
Each argument can be a literal Integer or Decimal number, a function returning a number, or a reference to a column containing numeric values.
注記
Within an expression, you might choose to use the corresponding operator, instead of this function. For more information, see Numeric Operators.
Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language.
Basic Usage
multiply(10,4)
Output: Returns the multiplication of 10 and 4, which is 40.
