Code:
$ awk -F'/' 'function isnum(x){return(x==x+0)}/P1/,/P2/{if(!/P1|P2/ && /10,9:.*/)print "value"++i,":",isnum($NF)?$NF:"NULL"}' file

scalar::util::numeric

Scalar::Util::Numeric(3pm)				User Contributed Perl Documentation				Scalar::Util::Numeric(3pm)

NAME

       Scalar::Util::Numeric - numeric tests for Perl scalars

SYNOPSIS

	   use Scalar::Util::Numeric qw(isnum isint isfloat);

	   foo($bar / 2) if (isnum $bar);

	   if (isint $baz) {
	       # ...
	   } elsif (isfloat $baz) {
	       # ...
	   }

DESCRIPTION

       This module exports a number of wrappers around perl's builtin "grok_number" function, which returns the numeric type of its argument, or 0
       if it isn't numeric.

TAGS

       All of the functions exported by Scalar::Util::Numeric can be imported by using the ":all" tag:

	   use Scalar::Util::Numeric qw(:all);

EXPORTS

   isnum
	   isnum ($val)

       Returns a nonzero value (indicating the numeric type) if $val is a number.

       The numeric type is a conjunction of the following flags:

	   0x01  IS_NUMBER_IN_UV	       (number within UV range - not necessarily an integer)
	   0x02  IS_NUMBER_GREATER_THAN_UV_MAX (number is greater than UV_MAX)
	   0x04  IS_NUMBER_NOT_INT	       (saw . or E notation)
	   0x08  IS_NUMBER_NEG		       (leading minus sign)
	   0x10  IS_NUMBER_INFINITY	       (Infinity)
	   0x20  IS_NUMBER_NAN		       (NaN - not a number)

   isint
   isuv
   isbig
   isfloat
   isneg
   isinf
   isnan
       The following flavours of "isnum" (corresponding to the flags above) are also available:

	   isint
	   isuv
	   isbig
	   isfloat
	   isneg
	   isinf
	   isnan

       "isint" returns -1 if its operand is a negative integer, 1 if it's 0 or a positive integer, and 0 otherwise.

       The others always return 1 or 0.
