how to round/remove traling “.0” zeros in pandas column?

Question

I\'m trying to see if I can remove the trailing zeros from this phone number column.

Example:

0
1      8.00735e+09
2      4.35789e+09
3      6.10644e         


        

Answer 1

use astype(np.int64)

s = pd.Series(['', 8.00735e+09, 4.35789e+09, 6.10644e+09])
mask = pd.to_numeric(s).notnull()
s.loc[mask] = s.loc[mask].astype(np.int64)
s

0              
1    8007350000
2    4357890000
3    6106440000
