A mobile can be made with 4 millimetres (mm) of wire. After making several mobiles of the same size using 117.6 millimetres (mm) of wire, how many centimetres (cm) of wire are left?
117.6 4 [OP_MOD] 10 [OP_DIV]
var_a = 117.6
var_b = 4
var_c = var_a % var_b
var_d = 10
var_e = var_c / var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
