QA testing has shown a potential issue with the precision of created orders.

Steps:

• place a partial order using cli or console cmd dxMakePartialOrder
• maker_size value changes from the original value posted:

Result:

Expected:

”BLOCK”,”maker_size”:”0.100000000000000000

_Note the zero at the end of the maker_size value._
