See egreg's comment, for the simplest solution for integer numbers in the range -2147483647 to 2147483647:
number000123⌴
number-000456⌴
Result: 123 and -456
The space, marked with ⌴ ends the parsing of the number and prevents accident if digits are following in the normal text.
This solution is expandable and can be used inside csname, label, typeout, for example.
Package bigintcalc
This package provides an expandable method for removing leading zeros from integer numbers that are arbitrary large. From the documentation:
bigintcalcNum ⟨x⟩
Macro
bigintcalcNumconverts its argument to a normalized integer
number without unnecessary leading zeros or signs. The result matches
the regular expression:0|-?[1-9][0-9]*
Example:
usepackagebigintcalc% plain TeX: input bigintcalc.sty
...
bigintcalcNum000123456789123456789123456789
bigintcalcNum-000123456789123456789123456789
Result: 123456789123456789123456789 and -123456789123456789123456789
The macro is expandable, the package can be used with lots of TeX flavors (LaTeX, plain TeX, iniTeX, ...)
Package siunitx
If the number is to be intended to be printed, package siunitx offers lots of options to format the number. By default, leading zeros are removed:
documentclassarticle
usepackagesiunitx
begindocument
num000123; num-000456
enddocument
Result: 123; -456
