[pdm-devel] [PATCH proxmox-yew-comp 02/15] remove needless casts

[Maximiliano Sandoval]

Fixes:

warning: casting to the same type is unnecessary (`f64` -> `f64`)
   --> src/rrd_graph_new.rs:514:23
    |
514 |                     + (((t - start_time) as f64 * width) as f64) / time_span
    |                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: try: `((t - start_time) as f64 * width)`
    |

warning: casting float literal to `f64` is unnecessary
   --> src/rrd_graph_new.rs:208:20
    |
208 |     while (range / (2.0 as f64).powi(l)) < 4.0 {
    |                    ^^^^^^^^^^^^ help: try: `2.0_f64`
