用python将十进制小数转换为二进制小数

Question

Answer 1

def tobin(data):
    tmp = data
    nNum=int(tmp)

    res=str(bin(nNum))+'.'
    exp=tmp-nNum

    index=10
    while(index>0):
        exp = exp * 2

        if(exp>=1):
            exp=exp-1
            res+='1'
        else:
            res+='0'
        index=index-1

    return res




if __name__ == '__main__':
    data = float(input(">>>"))
    print( tobin(data))
