floating point - Convert float 2-D array to integer 2-D array in Julia -
i know possible convert float64 int64 using convert function. unfortunately, doesn't work when applying convert 2-d array.
julia> convert(int64, 2.0) 2 julia> = [1.0 2.0; 3.0 4.0] 2x2 array{float64,2}: 1.0 2.0 3.0 4.0 julia> convert(int64, a) error: `convert` has no method matching convert(::type{int64}, ::array{float64,2 }) in convert @ base.jl:13 how convert 2-d array of floats 2-d array of ints?
what tried
i using following code, little verbose works. hoping there easier way though.
julia> = [1.0 2.0; 3.0 4.0] 2x2 array{float64,2}: 1.0 2.0 3.0 4.0 julia> b = array(int64, 2, 2) 2x2 array{int64,2}: 4596199964293150115 4592706631984861405 4604419156384151675 0 julia> = 1:2 j = 1:2 b[i,j] = convert(int64,a[i,j]) end end julia> b 2x2 array{int64,2}: 1 2 3 4 an answer doesn't work me

use int function:
julia> = rand(2,2) 2x2 array{float64,2}: 0.145651 0.362497 0.879268 0.753001 julia> int(a) 2x2 array{int64,2}: 0 0 1 1
