eps()

eps()

The distance between 1.0 and the next larger representable floating-point value of Float64.

Examples

julia> eps(Float64)
2.220446049250313e-16
julia> eps(Float32)
1.1920929f-7
julia> eps(BigFloat)
1.000000000000000000000000000000000000000000000000000000000000000000000000000004e-10000

The eps function returns the distance between 1.0 and the next larger representable floating-point value of the given floating-point type T.

Here are some examples of how to use the eps function with different floating-point types:

  1. Get the machine epsilon for Float64:

    julia> eps(Float64)
2.220446049250313e-16

  2. Get the machine epsilon for Float32:

    julia> eps(Float32)
1.1920929f-7
  3. Get the machine epsilon for BigFloat: 
    julia> eps(BigFloat)
1.000000000000000000000000000000000000000000000000000000000000000000000000000004e-10000

Please note that only floating-point types are valid arguments for the eps function.
