Hello, I want to be able to represent numbers that are really big in a Perl program. For example, consider the XML Schema built in simple type xsd:long, which is a 64 bit integer in the range [-9223372036854775808,-9223372036854775807] -- I want to be able to do the following:
1. read and store the scalar 2. use the number in arithmetic operations such as comparisons, addition, subtraction... 3. pack the number into a C long long int data type (i.e., a 64 bite representation). #1 shouldn't be a problem, as the scalar representation will probably remain "as string" until I put it in a context where Perl will need to convert it to a numerical value -- right? #2 should be OK as long as I am consistent using Math::BigInt. The problem starts, I think in #3: What should be the proper way to do this? I noticed that pack() and unpack() don't have a built in template for long long int. So -- my question is actually, how do I pack and unpack numbers that are beyond the scope of an int? Thanks -- Shlomo Yona [EMAIL PROTECTED] http://yeda.cs.technion.ac.il/~yona/ _______________________________________________ Perl mailing list [email protected] http://perl.org.il/mailman/listinfo/perl
