print_shortest
print_shortest(io, x)
Print the shortest possible representation, with the minimum number of consecutive non-zero digits, of number x, ensuring that it would parse to the exact same number.
Examples
julia> io = IOBuffer();
julia> print_shortest(io, 123.456)
5-element Array{UInt8,1}:
0x31
0x32
0x33
0x2e
0x34Common examples of its use:
-
Print the shortest representation of a floating-point number:
julia> io = IOBuffer(); julia> print_shortest(io, 3.14159) 6-element Array{UInt8,1}: 0x33 0x2e 0x31 0x34 0x31 0x35This example prints the shortest representation of the number
3.14159as a sequence of UTF-8 bytes. -
Print the shortest representation of an integer:
julia> io = IOBuffer(); julia> print_shortest(io, 1000) 4-element Array{UInt8,1}: 0x31 0x30 0x30 0x30It prints the shortest representation of the integer
1000. - Print the shortest representation of a negative number:
julia> io = IOBuffer(); julia> print_shortest(io, -42.42) 6-element Array{UInt8,1}: 0x2d 0x34 0x32 0x2e 0x34 0x32It prints the shortest representation of the negative number
-42.42.
Common mistake example:
julia> io = IOBuffer();
julia> print_shortest(io, "Hello")
ERROR: MethodError: no method matching print_shortest(::IOBuffer, ::String)In this example, the function print_shortest is called with a String argument, which is not supported. It's important to ensure that the argument x is a number that can be represented as a valid Julia number.
