BCP QUERYOUT how to change length to all decimal fields

Question

I export SQL tables to txt files (by the code below in ssms)
all the columns are exported well except decimal columns, which export 41 chars (I want 19 chars),
even the size column is 14(4)
how can I change the settings in order the column will export in the size I want?

notes:
bcp export 0.0 decimal value as .0000 as I need
my tables is very big can't use substring- a lot of columns and a lot of rows
