After multiplying a decimal by 1000, moving the decimal two places to the left equals 12.5. Find the original decimal.
12.5 10 2 [OP_POW] [OP_MUL] 1000 [OP_DIV]
var_a = 12.5
var_b = 10
var_c = 2
var_d = var_b ** var_c
var_e = var_a * var_d
var_f = 1000
var_g = var_e / var_f
print('{:.2f}'.format(round(var_g+1e-10,2)))
