round up?
1) 0% of 50 cents = 0 cents ; balance rm199.50
2) 6% of 50 cents = 3 cents ; balance rm199.47
3) 10% of 50 cents = 5 cents ; balance rm199.45
gst must be applied on service charge, so (1) surely not applicable. if you want me to choose (2) or (3), i rather choose (2) la. buat apa want to round up the gst from 6% to 10%.
Option 2 is the correct method
6% GST amount itself already, by default, rounded to 2 decimals (standard rounding mechanism).
e.g. 6% GST of RM0.50 service charge = RM0.03 (2 decimals, no rounding required).
Paid amount: RM200.00
Reload service charge: RM0.50
6% GST for reload service charge: RM0.03
Nett reload amount: RM199.47 (RM200.00 minus RM0.50 minus RM0.03)
