HI,

Here is the improved code.. In fact here i was trying to check string by mistake.. "second" is a string

i = random.uniform(-9.99999999999,9.99999999999)                
        j = random.randint(-499,499)                            
        k = random.uniform(-9.99999999999,9.99999999999)
        l = random.randint(-499,499)                            
        first = str(i) + 'EEX' + str(j)
        second = str(k) + 'EEX' + str(l)
        f.writelines(["[TEST COMPLEX_Real%0.0f]  conj(" % (n) + first + '+' + second + ")\n" ])
        second = atof(second)
        second = second * (-1)
        f.writelines(["[EXPECTED]" + first + "," + second + "\n [BINARY] 0\n[PRIORITY]\n" ])

i want to convert variable second to floating point number.

please help me to sort out this Issue.

Thanks in advance.
