# inf

inf(f)

Returns positive infinity of the floating point type `f` or of the same floating point type as `f`

## Examples

Sure! Here are some examples of how the `inf(f)` function can be used in Julia:

1. Get the positive infinity for Float64:

``````julia> inf(Float64)
Inf``````

This example returns the positive infinity value for the `Float64` type.

2. Assign positive infinity to a variable:

``````julia> x = inf(Float32)
Inf32``````

It assigns the positive infinity value of type `Float32` to the variable `x`.

3. Perform arithmetic operations with infinity:

``````julia> a = 10.0
10.0

julia> b = inf(Float64)
Inf

julia> c = a + b
Inf

julia> d = b / 2.0
Inf``````

In this example, basic arithmetic operations like addition and division are performed with `inf`. The result is always `Inf`.

Common mistake example:

``````julia> inf(Float16)
ERROR: MethodError: no method matching inf(::Type{Float16})``````

In this case, the mistake is using the `Float16` type with `inf`. The `Float16` type does not support the `inf` function, so it results in a `MethodError`. Make sure to use a floating-point type that supports `inf` to avoid such errors.
