version 0.005; 2007-09-02
* in t/purity.t, modify purity test on dualvar(0, "0") to operate
appropriately on older Perls where this has a different numeric
value from 0
* in t/purity.t, fix a skip count for the case where dualvar() is
not available
version 0.004; 2007-08-16
* in t/purity.t, fix a skip count for the case where floating point
zero is unsigned
version 0.003; 2007-08-15
* in t/purity.t, modify purity test on dualvar(+0.0, "0") to operate
appropriately on older Perls where "0" numifies to a floating
point zero, and add a test for dualvar(0, "0")
version 0.002; 2007-01-25
* add is_pure_string() and is_pure_number() functions that determine
how complicated a string scalar is
* in documentation for is_number(), reference Scalar::Number and
Data::Integer
* correct version requirement of Scalar::Util in module, making it
consistent with the dependency listed in Makefile.PL
version 0.001; 2006-08-03
* bugfix: in is_number(), check whether numeric conversion warns, rather
than using looks_like_number(), to avoid being confused by dualvars
* in t/ref.t, skip *foo{FORMAT} tests on older Perls that don't provide
that facility
* refer to Data::Float for classification of floating point values
* versioned dependencies in .pm
* declare module dependencies in Makefile.PL
* correct .cvsignore (had copy&modify detritus)
* include Changes file
version 0.000; 2004-03-20
* initial released version
