Let me educate you. =) We are mainly talking about
In this time of web-services we frequently do encoding and decoding on
It is preferable that these encode and decode transformations are fast.
Since we migrated from mainly having text as list to mostly binaries we
are lacking a solid and fast binary to integer function. (In addition,
it always seems stupid that I have to do: "b2i(I) ->
It has never been a pressing need. It still isn't. It is more in the
"would be nice to have" category.
Yet another way to go would be to have:
Just fire and forget.
and ofc (!)
The two latter function would naturally produce iodata in an arbitrary
fashion but satisfying the textual iodata representation of the float or
integer we used as input.
for convenience we should also have
