Weird metronome BPM display behavior

[hiderikzki]

Type

Game behaviour

Bug description

BPM displayed on the metronome is one lower on some specific values, mainly noted down 29 and 55 and all doubles of it (110, 220, 440, etc.)

The metronome also displays floating point BPM way too precisely compared to the actual BPM field, while the BPM field displays only up to 2 decimals, the metronome BPM display shows up to full float or double precision (which ever is being used in code)

I've found this really inconsistent and different problems in many cases

Beatmaps that break things (off-by-one):

• https://osu.ppy.sh/beatmapsets/2281269#osu/4863637
• https://osu.ppy.sh/beatmapsets/2274845#osu/4855187
• https://osu.ppy.sh/beatmapsets/1988818#osu/4131547 (at time 00:07:738 and 00:08:359 has float non-sense, the rest is off-by-one)
• https://osu.ppy.sh/beatmapsets/1946744#osu/4033895 (set ticks to triplets and hold control for multiplied BPM for float nonsense)
• https://osu.ppy.sh/beatmapsets/1951939#osu/4041880 (hold control)
• https://osu.ppy.sh/beatmapsets/1109083#osu/2317735 (most seem fine, hold control at time 00:16:422 for float non-sense)
• https://osu.ppy.sh/beatmapsets/1376486#osu/2857448 (heavily variable BPM song, issues start from 00:29:279, float non-sense at 02:06:547)
• https://osu.ppy.sh/beatmapsets/2150088#osu/4529671 (173, shown as 172)
