SQL Script Calculation View: CE_CALC variable conversion

Hello,

I am trying to replace a field value that contains '1,001.000 lb' with '1001.000'.  If at all possible I would further like to convert '1001.000' to a number.  Is it possible to accomplish the above in a CE_CALC function?

This is what the Oracle SQL code would look like for this requirement:

select to_number(replace(replace('1,001.000 lb', ' lb', ''), ',', ''))
from dual

Result: 1001

Thanks,
Victoria
