    Assume that the number is AB.CD

    sum of my whole number is equal to the sum of my decimal number

    A+B=C+D

    my tenths is half of my hundredths

    2C=D

    my ones is twice my tenths

    2B=A

    my hundredths is 8
    D=8

    so from 2C=D, C=4

    A+B=C+D=4+8=12

    A+B=12 and 2B=A

    2B+B=12 so B=4 and A=8

    so number is

    84.48

    which also agrees with

    all my digit are even
