How to solve this issue?

I am doing encryption of an image. In between, there is a step to do bitxor. For that one input is decimal values and the other is a hexa decimal value. I cannot round the decimal values. What is the other option to do bitxor?

Y1=dec2hex(bitxor(hex2dec(plain_1), hex2dec(Y11)));

plain_1 =

    Columns 1 through 7

      5.5910    4.5032    5.9233    5.6765    5.7605    4.4733    5.8600

    Columns 8 through 14

      5.8760    5.4787    5.4357    4.6258    5.2075    5.1449    5.5539

    Columns 15 through 16

      4.0129    4.0672

Y11 =

E5
B1
CD
6E
8C

How to do bitxor for the above inputs?
