Donate less than a dollar

Hello,
I have a client who wants to offer suggested donation amounts that are not even dollars. For example, $26.25/month (recurring donation). But Joom Donation only processes $26.00, not recognising the $0.25 amount.
How do I get this so donors can give amounts that are not in even dollar amounts?
What am I missing?
Thanks,
Ron

I set my predefined amount to 10.25 and it shows up on the form that way. Are you saying it does not actually process the right amount? I can't imagine the payment gateway would care. 

Hi Dave,I tried a donation of $2.25 ....see screenshot below. When I go to process the donation, an error message comes up asking me to change this to $2.00 or $3.00This is using Stripe. I have also tried this with PayPal...same thing.Thanks any help....

What's the minimum amount in the Global Configuration set to? Is it set to $3 for the minimum? The payment gateway is not controlling that setting. I don't know if gateways have minimums. They only recommend not setting it too low so criminals are not testing stolen cards on the form.

I set the minimum to $2.00 for test purposes. I made a few $2 donations, no problem.
On another site I had a person trying to donate an amount like $750.50 (I don't remember the exact amount), but they were not allowed to donate without rounding up or down (750, or 751).
So, I suspect it's some setting in Joom Donation.
Thanks for looking into this.

Hi Rpierce,
It seems you are having with Custom Donation amount field, you can raise new ticket on category: Joom Donation and provide your site url with super admin account. I will create the override layout of Donation form and solve the issue for you

Why would anyone need to donate in less than $1 amounts though? Especially when you donate $750 dollars. What's $.50 for?
