Round to nearest 5 with numpy

Question

df
        A
0  503.36
1  509.80
2  612.31
3  614.29

I want to round to nearest 5 in a new B column, using numpy if possible.

Output should be:

        A        B
0  503.36   505.00
1  509.80   510.00
2  612.31   610.00
3  614.29   615.00

Answer 1

Since you mention numpy

np.around(df.A.values/5, decimals=0)*5
Out[31]: array([505., 510., 610., 615.])
