Basically, given a float point number, say

f=0.25

I want

'25e-02'

I would only consider numbers with two decimals. How can I do this without multiplying 100??

If I simply do '%.1e'%0.25, I get '2.5e-01', which is not what I want. I wonder if there is any way that I can choose the number in the exponent part, namely the xx in e-xx.

The answer is no, Python doesn't provide you a way to do that directly. – John Szakmeister Apr 25 '19 at 11:43
@JohnSzakmeister Okay, thanks. Then I guess I need to make my own function to make it... – le4m Apr 25 '19 at 11:44
