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
