3.1.1 Exact Functions

Consider the n-ary function tex2html_wrap_inline33809 . The function g is exact if:

math10887

this is equivalent to tex2html_wrap_inline33813 being closed over tex2html_wrap_inline32371 . If g is exact then tex2html_wrap_inline33819 . The functions |x|, x, -x, tex2html_wrap_inline33827 , tex2html_wrap_inline33829 , tex2html_wrap_inline33831 , and tex2html_wrap_inline33833 are all exact. Allow tex2html_wrap_inline33805 to be an exact implementation of one of the preceding exact functions. An implementation of tex2html_wrap_inline33801 or tex2html_wrap_inline33803 may simply invoke tex2html_wrap_inline33805 .
