I'm developing a program that makes some floating points calculations. Is there any way to test my functions (which deliver floats) with doctests?

推荐答案

当然，请根据对浮点数显示精度的了解，以合理的格式对浮点数进行格式化-例如，如果期望精度为2小数点后的数字，您可以使用:

Sure, just format the floats with a reasonable format, based on your knowledge of what precision you expect them to exhibit -- e.g, if you expect accuracy to 2 digits after the decimal point, you could use:

''' Rest of your docstring and then...

    >>> '%.2f' % funcreturningfloat()
    '123.45'

'''
