Converting String to Number in Julia
Code
To convert a string str
to a number of type type
, use parse(type, str)
.
julia> parse(Int, "21")
21
julia> parse(Float64, "3.14")
3.14
You might wonder why we can’t do something like Int64("21")
as in Python… That’s because changing ‘“21”’ into 21
is not about changing types but interpreting the string "21"
as a number, which justifies the use of parse
1.
