Formatting float with zero padding and implied decimal

Is there a way for mini-languages ​​for this format?

cram a float to 9999 ^ 99 zero padded ^ - implied decimal number.

I did it

for x in (450.5, 50.0, 50.0043, 9999.989,0.5):
    print ('{0:06}'.format(round(x,2)).replace('.','')+'000')[0:6]

but I felt a bit dirty afterwords ... so I changed it ...

I know that I can break the float and bring it back together

for x in (450.5, 50.0, 50.0043, 9999.989,0.5, 4):
    print '{0:04}{1:0<2}'.format(int(x),int(x % 1 * 100))

it didn't make me feel much better.
I know what I'm doing, but just because I wrote it ...

Who has a great way that is concise and clear? Or is this code clear enough?
