Expand description

Computes a binary math function for input arrays using a specified function and apply rescaling to given precision and scale. Generic types:

  • 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>
