Hello,
After an upgrade from fedora 13 to fedora 14, my application fails
with:
PDL::LinearAlgebra::Real needs to be recompiled against the newly
installed PDL at /usr/lib64/perl5/DynaLoader.pm line 223
I just reinstall perl::LinearAlgebra
which contains Real.
PDL has also been recompiled.
Hello,
I need to convert the result of an aritmetic operation on 2
bignum into a normal float (ie double)
I did not find a way to do this.
no bignum ;
my $res = $A - $B ;
gives me always a bignum ($res) if $A and $B are bignum.
Thank.
