Why it can't turn the 32-bit binary Integer. The parseInt (10000000100000001000000010000000, 2)
How will the binary to decimal method using

Is the sign bit integer that high turn 31 two hexadecimal

Then how to turn a 32-bit

That how to turn a 32-bit

Int is a 32-bit but highest level is the sign bit, that is to say, only 31 integer values a. Paresint can only identify 31 2 into a positive number, you enter a 32-bit copy a ceiling
