Hello,

(Stripping trailing CRs from patch; use --binary to disable.)
patching file FLOAT.spad
I guessed it has to be applied on the extracted FLOAT.spad file during
the build. It works fine thanks but is this expected:
Before and after
(1) -> toString(3.7,30)
(1) "3.700000000000000000002684354560"
Type: String
Time: 0.04 (OT) = 0.06 sec
(2) -> )lib FLOAT
Float is now explicitly exposed in frame frame1
Float will be automatically loaded when needed from
/home/greg/Git/jlfricas/FLOAT.NRLIB/FLOAT
(2) -> toString(3.7,30)
(2) "3.700000000000000000002710505431"
Type: String
Using 30 is of course not judicious since by default digits() = 20, I
wonder what can be returned with this argument.
