I want a function like
frexp, but that returns an integer (of the same size of the floating point) and an exponent. Currently I have tried the following implementation:
julia> inexp(x::T) where T <: Base.Math.IEEEFloat = begin m, ex = frexp(x) b = Base.Math.significand_bits(T) mi = trunc(Integer, m * exp2(b)) return mi, ex - b end inexp (generic function with 1 method) julia> inexp(2.3) (2589569785738035, -50)
I am not too familiar with floating points, so I wonder if there anything I should look out for that I am not handling properly in my implementation here.
