Hi,
Why does the Javascript function call isNaN(123.) return false? Is this a universally acceptable number or will it cause errors downstream?
I'm validating whether a value is a valid decimal using isNaN along with split. Are there cross-browser issues with isNaN? Should I use a bespoke implementation?
Thanks.
