This coding is make by CHU KUN QUAN in INTI University Nilai) I declare this to avoid plagiarism for this feb 25 2023 assignment to lecture Ms Chong if you found my article here.)

Need help, to make it allow to user enter exact amount and can change money to user after user entered greater amount.

on the receipt function if (paymentAmount >= roundedTotal - 0.001 && paymentAmount <= roundedTotal + 0.001) then it only allow user enter exact amount, if greater than exact amount it will not change, it will show payment unsuccessful.

if (paymentAmount >= roundedTotal) It will change but it can't enter exact amount For example 0.38 onglai, user enter payment amount 0.38, it will show unsufficient payment. (Give me your full coding after updated version, tq)

Can access the full code below ( chegg only allow 16000 character)
