+Subject: [PATCH] download: format byte unit with 1 decimal place precision
+
+Prior to v0.24.1 the output when processing a stream of disk image
+input the output would write with 1 decimal place of precision:
+
+```
+Read disk 118.2 MiB/2.6 GiB (4%)
+Read disk 157.0 MiB/2.6 GiB (5%)
+Read disk 300.1 MiB/2.6 GiB (11%)
+Read disk 450.6 MiB/2.6 GiB (16%)
+Read disk 515.2 MiB/2.6 GiB (19%)
+```
+
+After v0.24.1 it has many decimal places of precision:
+
+```
+Read disk 138.2265625 MiB/2.59765625 GiB (5%)
+Read disk 265.6722106933594 MiB/2.59765625 GiB (9%)
+Read disk 399.67578125 MiB/2.59765625 GiB (15%)
+Read disk 519.40625 MiB/2.59765625 GiB (19%)
+Read disk 597.5625 MiB/2.59765625 GiB (22%)
+```
+
+This is likely due to 68198d0. Let's get back the previous formatting.
