• I have visited the source website, and in particular, read the known issues
• I have searched through the issue tracker for duplicates
• I have mentioned version numbers, operating system and environment, where applicable:

print(tqdm.__version__)  # 4.26.0
print(sys.version)  # 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 17:00:18) [MSC v.1900 64 bit (AMD64)]
print(sys.platform)  # win32

All numbers greater than 999 in the postfix are shown in the progress bar in scientific notation.
Examples:

As you can see (at least for smaller numbers) it's

• harder to read
• less precise
• more verbose

Is this the intended behaviour? If so, how can I disable it? The unit_scale and unit_divisor params in the constructor looked promising, but they don't seem to be related to this.

Here's a MWE:

from tqdm import tqdm

with tqdm() as bar:
    bar.set_postfix({"some_number": 1000})

which outputs:

0it [00:00, ?it/s, some_number=1e+03]
