LE_CONV : conv
STRUCTURE
reduceLib
SYNOPSIS
Proves result of less-than-or-equal-to ordering on two numerals.
LIBRARY
reduce
DESCRIPTION
If m and n are both numerals (e.g. 0, 1, 2, 3,...), then LE_CONV "m <= n" returns the theorem: 
   |- (m <= n) = T
if the natural number denoted by m is less than or equal to that denoted by n, or 
   |- (m <= n) = F
otherwise.
FAILURE
LE_CONV tm fails unless tm is of the form "m <= n", where m and n are numerals.
EXAMPLE
#LE_CONV "12 <= 198";;
|- 12 <= 198 = T

#LE_CONV "46 <= 46";;
|- 46 <= 46 = T

#LE_CONV "13 <= 12";;
|- 13 <= 12 = F
