The new masternodes are now built in the way that each masternode share percent is an integer value.
Shares could be 1%, 2%, 3%, 45%, 74% but not 74.65%. This has been done to avoid extra small shares to fill the masternode up that could arise before.

Bitcoin Green node for example requires 2500 BITG. You could buy shares of 25 BITG, 50 BITG, 75BITG, 2025 BITG etc.
However 26.7232 BITG share is not allowed anymore. If you send 26.7232 BITG to the service you get 1.7232 back when the masternode is being started.
