 Syntax
   func long iround extern
   param value dbl eNumber

 Arguments
   eNumber is the number to convert.

 Return
   The rounded value of the passed numeric.

   #define EXAMPLE_MATH
   #include example.hdr

   proc Test_iround
   ? iround( -10.4 )      // prints -10
   ? iround( -10.5 )      // prints -11
   ? iround(  10.4 )      // prints  10
   ? iround(  10.5 )      // prints  11
   endproc

   proc main
   Test_iround()
   endproc
