How do I ignore 0 value for price validation using pattern?

I have problem with my price validation (pattern-JavaScript).

My pattern does not accepts values that I want such as:

• 101.00
• 110.00
• 1000.00
• 0.50

My pattern accepts values such as:

• 1.00
• 1.10
• 1.11
• 11.11

Right now, my pattern is ^([1-9]+.)(\d{2})$
