Redeem loyalty point with full amount of sale invoice amount

[tespheakdeyesoftix]

Hi Team,
First thank for awesome erp.
I use loyalty point program feature in erpnext and it working perfect for earning point and my customer is happy with it.
But when redeem all customer need to redeem full amount of sale invoice amount when they have enough point.
Now we cannot do that because redeem accept only int number and cannot enter over max point.

Most of sale invoice amount always have decimal number and when redeem point decimal number always leave as outstanding balance and it force customer to pay with cash. It is very inconvenient for them.

Please anyone have experience with this issue advice how can I solve this problem? Or Am I miss configuration somewhere?

Thanks,
