" Numbers. Matching J numbers is difficult. In fact, the job cannot be done
" with regular expressions alone. Below is a sketch of the pattern used. It
" accepts most well-formed numbers and rejects most of the ill-formed ones.
" See http://www.jsoftware.com/help/dictionary/dcons.htm for reference.
"
" "double1" and "double2" patterns:
" (_?\d+(\.\d*)?|_\.\d+)([eE]_?\d+)?
" (_?\d+(\.\d*)?|_\.\d+|\.\d+)([eE]_?\d+)?
"
" "rational1" and "rational2" patterns:
" \k<double1>(r\k<double2>)?|__?
" \k<double2>(r\k<double2>)?|__?
"
" "complex1" and "complex2" patterns:
" \k<rational1>((j|a[dr])\k<rational2>)?
" \k<rational2>((j|a[dr])\k<rational2>)?
"
" "basevalue" pattern:
" _?[0-9a-z]+(\.[0-9a-z]*)?|_?\.[0-9a-z]+
"
" all numbers:
" \b\k<complex1>([px]\k<complex2>)?(b\k<basevalue>)?(?![0-9A-Za-z_.])
