[julia-users] Re: float approximation of bigfloat

['Stéphane Laurent' via julia-users]

convert works fine on a single BigFloat but it doesn't apply to an array ?

julia> x = BigFloat("2.13")

2.130000000000000000000000000000000000000000000000000000000000000000000000000003e+00
 with 256 bits of precision


julia> convert(Float64,x)

2.13


julia> convert(Float64, [x x])

MethodError(convert,(Float64,
