adjustment for proper calculation and display of delegated values and usd counterpart (316)

After the last fix for VESTS/HP conversion, there was still an issue with the proper calculation affected by decimal point inclusion and extra spacing prior to VESTS wording, which affected final output whether in HP or USD in different cases.

This MR is to fix those issues (issue #316 (closed))

Pre fix (incorrect value displayed under Delegated HP)

Matching VESTS value: (75,955.308014 VESTS atm equals after / ~1708 = ~ 44.47HP )

Post fix
