Comment(by pfctdayelise):

 It's not just Windows, also on Linux (Fedora 14) with Python 2.7.1.

 >>> 'hello {:.1f}'.format(1.39)
 'hello 1.4'

 >>> 'hello {:.1f}'.format(np.float64(1.39))
 'hello 1.4'

 >>> 'hello {:.1f}'.format(np.float32(1.39))
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 ValueError: Unknown format code 'f' for object of type 'str'
