# title:        Operations when using "SET DECFLOAT BIND BIGINT,n" with result of 11+ digits, fail with "Decimal float invalid operation"
# decription:   
#                   Confirmed bug on: 4.0.0.1633 SS: FAILED.
#                   Checked on 4.0.0.1646 CS: 1.219s.
#               
#                   10.12.2019. Updated syntax for SET BIND command because it was changed in 11-nov-2019. 
#                   Replaced 'bigint,3' with numeric(18,3) - can not specify scale using comma delimiter, i.e. ",3"
#               
#                   Checked on: WI-T4.0.0.1685.
