pyspark convert scientific notation to string

Question

Something what should be really simple getting me frustrated.
When reading from csv in pyspark in databricks the output has a scientific notation:

Name Code
AA 6.44E+11
BB 5.41E+12

how to convert it to string? Here is the expected output. Note, Code can have any lenght. Need both, Name and Code as a result in dataframe.

Name Code
AA 644217000000
BB 5413150000000

I tried this pyspark-how-to-remove-scientific-notation-in-csv-output but it getting me error on "avg".
The simpler the better. TIA

Hello @braxx ,
Thanks for the ask and using Microsoft Q&A platform .

You mentioned that the file is CSV , but there is no comma seprated field which you have shared .

You can try the below code .

from pyspark.sql.functions import format_string

---

df.select('Name',format_string('%.1f',df.Code.cast('float')).alias('converted')).show()

Output :
+----+---------------+
|Name| converted|
+----+---------------+
| AA| 643999989760.0|
| BB|5409999945728.0|
+----+---------------+

Please do let me know how it goes .
Thanks
Himanshu
