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:

Get the positive infinity for Float64:
julia> inf(Float64) Inf
This example returns the positive infinity value for the
Float64
type. 
Assign positive infinity to a variable:
julia> x = inf(Float32) Inf32
It assigns the positive infinity value of type
Float32
to the variablex
. 
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 alwaysInf
.
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 floatingpoint type that supports inf
to avoid such errors.
