NEQ_CONV : conv
STRUCTURE

SYNOPSIS
Proves equality or inequality of two numerals.
LIBRARY
reduce
DESCRIPTION
If m and n are both numerals (e.g. 0, 1, 2, 3,...), then NEQ_CONV "m = n" returns the theorem: 
   |- (m = n) = T
if m and n are identical, or 
   |- (m = n) = F
if m and n are distinct.
FAILURE
NEQ_CONV tm fails unless tm is of the form "m = n", where m and n are numerals.
EXAMPLE
#NEQ_CONV "12 = 12";;
|- (12 = 12) = T

#NEQ_CONV "14 = 25";;
|- (14 = 25) = F
