Thanks @viirya I had forgotten about this ... this is the relevant code in
sql/planner.rs, for reference
```rust
// Parse number in sql string, convert to Expr::Literal
fn parse_sql_number(n: &str) -> Result<Expr> {
// parse first as i64
n.parse::<i64>()
.map(lit)
// if parsing as i64 fails try f64
.or_else(|_| n.parse::<f64>().map(lit))
.map_err(|_| {
DataFusionError::from(ParserError(format!(
"Cannot parse {} as i64 or f64",
n
)))
})
}
```
