hypot

hypot(x, y)

Compute the $\sqrt{x^2+y^2}$ avoiding overflow and underflow

Examples

julia> hypot(3, 4)
5.0

julia> hypot(0.5, 0.5)
0.7071067811865476

julia> x = 1e100;
julia> y = 1e-100;
julia> hypot(x, y)
1.0000000000000002e100

Common mistake example:

julia> hypot("3", 4)
MethodError: no method matching hypot(::String, ::Int64)

In this example, the hypot function expects numerical arguments, but a string was provided instead. Make sure to pass the correct argument types to the hypot function.
