This isn't a bug, it's a natural consequence of the limited precision of
the float4 datatype. The constant "0.11" defaults to type double
precision, and there is no float4 value that exactly equals the double
precision value of 0.11. Try casting the constant to float4 explicitly,
or putting quotes around it.
