Random Number in julia

Question

I want to make a random number between 1 and 30 I read the document but i can't find a method for do it

for example we do it in php by

 rand(1 , 30);

How can i handle it

Answer 1

It's explained in the docs https://docs.julialang.org/en/v1/stdlib/Random/#Base.rand

rand([rng=GLOBAL_RNG], [S], [dims...])

Pick a random element or array of random elements from the set of values specified by S; S can be

• an indexable collection (for example 1:9 or ('x', "y", :z)),
• an AbstractDict or AbstractSet object,
• a string (considered as a collection of characters), or
• a type: the set of values to pick from is then equivalent to typemin(S):typemax(S) for integers (this is not applicable to BigInt), to [0,1)[0, 1)[0,1) for floating point numbers and to [0,1)+i[0,1)[0, 1)+i[0, 1)[0,1)+i[0,1) for complex floating point numbers;

S defaults to Float64. When only one argument is passed besides the optional rng and is a Tuple, it is interpreted as a collection of values (S) and not as dims.

For your example it would be

rand(1:30)

Answer 2

You can pass ranges to the rand function to generate a number between two other numbers, included:

julia> rand(1:30)
24

julia> rand(1:30)
18
