Venkata Ramana G commented on SPARK-3268:
-----------------------------------------
Problem:
double, decimal and float are identified under fractional type hierarchy
as per Scala, % (rem) function is implemented under integral type hierarchy.
Currently there is no mechanism exists to allow fractional type using integral
operations.
Solution:
Scala provides overridden classes like DoubleAsIfIntegral, FloatAsIfIntegral,
BigDecimalAsIfIntegral to allow these types to work with integral operators.
So we can add asIntegral to FractionalType to support calling Integral related
functions.
i2 function can call functions on asIntegral to execute the same.
Implemented the same, writing test cases is pending, will submit the patch for
the same.
> DoubleType should support modulus
