If I have an 8-bit linear filtered texture that I am sampling from a fragment program (running in 24 bit precision), can I get out a color value that is not representable by an 8-bit number?

For example, if I had a texture that had rgb(0,0,232) and rgb(0,0,233) in adjacent texels and I sampled half way between them, could I get rgb(0,0,232.5) out? (I realize that they will be mapped to [0,1], but it's easier to explain with ints).

Thanks,
