Function calculate_binary_decimal_math_cast 

pub fn calculate_binary_decimal_math_cast<L, R, O, F>(
    left: &dyn Array,
    right: &ColumnarValue,
    fun: F,
    precision: u8,
    scale: i8,
    cast_target: &DataType,
) -> Result<Arc<PrimitiveArray<O>>>
where
    L: DecimalType,
    R: ArrowPrimitiveType,
    O: DecimalType,
    F: Fn(L::Native, R::Native) -> Result<O::Native, ArrowError>,
    R::Native: TryFrom<ScalarValue>,

Computes a binary math function for input arrays using a specified function and applies rescaling to given precision and scale.

It casts the right operand to cast_target instead of the default R::DATA_TYPE to preserve the right operand scale.

Type Parameters

• L: Left array decimal type
• R: Right array primitive type
• O: Output array decimal type
• F: Functor computing fun(l: L, r: R) -> Result<OutputType>

Arguments

• left: Left input array
• right: Right input array or scalar value
• fun: Function of type F
• precision: Precision to apply to output decimal array
• scale: Scale to apply to output decimal array
• cast_target: Data type to cast right operand to before applying function
