### Timing Calculations: Separate Calculation and Rounding

Source: https://github.com/imr-framework/pypulseq/blob/master/examples/scripts/STYLE_GUIDE.md

Provides an example of correctly calculating and rounding timing delays by splitting the process into two distinct steps.

```python
# Good: two separate steps
te_delay = te - pp.calc_duration(gx_pre) - gz.fall_time - gz.flat_time / 2 - pp.calc_duration(gx) / 2
te_delay = np.ceil(te_delay / seq.grad_raster_time) * seq.grad_raster_time

# Avoid: combined in one expression
te_delay = np.ceil(
    (te - pp.calc_duration(gx_pre) - gz.fall_time - gz.flat_time / 2 - pp.calc_duration(gx) / 2)
    / seq.grad_raster_time
) * seq.grad_raster_time
```
