REAL_INT_GE_CONV : conv

SYNOPSIS
Conversion to prove whether one integer literal of type :real is >= another.

DESCRIPTION
The call REAL_INT_GE_CONV `c1 >= c2` where c1 and c2 are integer literals of type :real, returns whichever of |- c1 >= c2 <=> T or |- c1 >= c2 <=> F is true. By an integer literal we mean either &n or -- &n where n is a numeral.

FAILURE CONDITIONS
Fails if applied to a term that is not the appropriate inequality comparison on two permitted integer literals of type :real.

EXAMPLE
  # REAL_INT_GE_CONV `&7 >= &6`;;
  val it : thm = |- &7 >= &6 <=> T

COMMENTS
The related function REAL_RAT_GE_CONV subsumes this functionality, also applying to rational literals. Unless the restriction to integers is desired or a tiny efficiency difference matters, it should be used in preference.
