-DESCRIPTION
-        These functions provide information on the floating point
-        argument supplied.
-
-        There are five major number formats -
-        o+
-        o zero
-         a number which contains all zero bits.
-        o subnormal
-         Is used to represent  number with a zero exponent, but a non zero fract
-ion.
-         o normal
-          A number with an exponent, and a fraction
-        o infinity
-          A number with an all 1's exponent and a zero fraction.
-        o NAN
-          A number with an all 1's exponent and a non zero fraction.
-
-        o-
-
-        <<isnan>> returns 1 if the argument is a nan. <<isinf>>
-        returns 1 if the argument is infinity.  <<finite>> returns 1 if the
-        argument is zero, subnormal or normal.
-
-        The <<isnanf>>, <<isinff>> and <<finitef>> perform the same
-        operations as their <<isnan>>, <<isinf>> and <<finite>>
-        counterparts, but on single precision floating point numbers.
