I guess datafusion use `f64` by default(you need `CAST(1.3 AS float)`).
```rust
#[tokio::test]
async fn dev_test()->Result<()>{
let ctx = SessionContext::new();
ctx.sql("create table test(col float);").await?.show().await?;
ctx.sql("insert into test values (1.1), (1.2), (1.3), (1.4),
(1.5);").await?.show().await?;
ctx.sql("select * from test where col > CAST(1.3 AS
float);").await?.show().await?;
ctx.sql("select * from test where col < CAST(1.3 AS
float)").await?.show().await?;
Ok(())
}
```
It print out following
```
++
++
+-------+
| count |
+-------+
| 5 |
+-------+
+-----+
| col |
+-----+
| 1.4 |
| 1.5 |
+-----+
+-----+
| col |
+-----+
| 1.1 |
| 1.2 |
+-----+
```
Tell me if it works in datafusion-cli.
