For a number that should have been divided by 18, I mistakenly divided it by 1.8, and the quotient was 21 and the remainder was 2. Find out the correct value that should have been calculated, and round it to two decimal places.
21 1.8 [OP_MUL] 2 [OP_ADD] 18 [OP_DIV] 2 [OP_ROUND]
var_a = 21
var_b = 1.8
var_c = var_a * var_b
var_d = 2
var_e = var_c + var_d
var_f = 18
var_g = var_e / var_f
var_h = 2
var_i = round(float(var_g)+1e-10, var_h)
print('{:.2f}'.format(round(var_i+1e-10,2)))
