[jira] [Created] (ARROW-9891) [Rust] [DataFusion] Make math functions support f32

Jorge created ARROW-9891:
----------------------------

             Summary: [Rust] [DataFusion] Make math functions support f32
                 Key: ARROW-9891
                 URL: https://issues.apache.org/jira/browse/ARROW-9891
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust, Rust - DataFusion
            Reporter: Jorge
            Assignee: Jorge


Given a math function `g`, we compute g(f32) using g(cast(f32 AS f64)).

The goal of this issue is to make the operation be cast(g(f32) AS f64) instead.

Since computations on f32 are faster than on f64, this is a simple optimization.
