Julia: eps(): Get distance between adjacent floating point numbers

‘eps()’ method available in two forms.

Method	Description
eps()	Returns the distance between 1.0 and the next larger representable floating-point value of Float64.
eps(x)	Returns the distance between 1 and the next larger representable floating-point value of the same data type as x.

julia> eps()
2.220446049250313e-16

julia> eps(2.3)
4.440892098500626e-16

julia> eps(2.9)
4.440892098500626e-16

julia> eps(15.4)
1.7763568394002505e-15

As you observe above snippet, the distance between two adjacent floating point numbers is not same, it is smaller for smaller values and larger for larger values.
