It’s worth mentioning the built in behavior for how floats are rendered using the raw format strings. If you know in advance where your fractional part lies with respect to 0.5 you can leverage the format string you originally attempted but discovered it fell short from rounding side effects "{:0.0f}". Check out the following examples…
>>> "{:0.0f}".format(1.999)
'2'
>>> "{:0.0f}".format(1.53)
'2'
>>> "{:0.0f}".format(1.500)
'2'
>>> "{:0.0f}".format(1.33)
'1'
>>> "{:0.0f}".format(0.501)
'1'
>>> "{:0.0f}".format(0.5)
'0'
>>> "{:0.0f}".format(0.1)
'0'
>>> "{:0.0f}".format(0.001)
'0'
As you can see there’s rounding behavior behind the scenes. In my case where I had a database converting ints to floats I knew I was dealing with a non fractional part in advance and only wanted to render in an html template the int portion of the float as a workaround. Of course if you don’t know in advance the fractional part you would need to carry out a truncation operation of some sort first on the float.
