3.1.3 Provided Functions

Consider the n-ary function tex2html_wrap_inline33809 , with implementations of tex2html_wrap_inline33803 and tex2html_wrap_inline33801 provided. Consider the m-ary function tex2html_wrap_inline33863 , along with n m-ary functions tex2html_wrap_inline33869 which are exact over tex2html_wrap_inline32371 . If

math10933

then

math10938

and

math10944

An implementation of tex2html_wrap_inline33873 invokes tex2html_wrap_inline33801 with arguments given by exact implementations of tex2html_wrap_inline33877 ; an implementation of tex2html_wrap_inline33879 similarly uses tex2html_wrap_inline33803 . Examples include:

math10954

The following examples demonstrate another method for computing common constant functions:

math10962

This method is usually preferable to the high precision method outlined in the previous subsection, as it is more portable and easily implemented. This method is, of course, restricted to those functions and constants which may be directly constructed from the provided operators.
