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.
