Consider values in test.pdb
Code:
ATOM      1  CAY ALA X   2      14.962  52.147  1.00  1.00       DIAL

Now, on my calculator
Quote:
sqrt(14.962^2 + 52.147^2 + (-10.171)^2)
gives 55.196


awk '{print sqrt($7^2 + $8^2 + $9^2)}' test.pdb
gives 54,7723



Could someone please try to explain this?




Consider a more difficult case called test2.pdb
Code:
ATOM      1  CAY ALA X   2      14.962  52.147 -10.171  1.00   1.00      DIAL
ATOM      5  CY  ALA X   2      14.566  51.759 -11.567  1.00  1.00       DIAL

Code:
awk 'BEGIN{s=0}{s = s + $7^2 + $8^2 + $9^2}END{print sqrt(s)}'  test2.pdb

gives

NAME
Palm::Address - Handler for Palm AddressBook databases SYNOPSIS
use Palm::Address; DESCRIPTION
The Address PDB handler is a helper class for the Palm::PDB package. It parses AddressBook databases. AppInfo block The AppInfo block begins with standard category support. See Palm::StdAppInfo for details. Other fields include: $pdb->{appinfo}{lastUniqueID} $pdb->{appinfo}{dirtyFields} I don't know what these are. $pdb->{appinfo}{fieldLabels}{name} $pdb->{appinfo}{fieldLabels}{firstName} $pdb->{appinfo}{fieldLabels}{company} $pdb->{appinfo}{fieldLabels}{phone1} $pdb->{appinfo}{fieldLabels}{phone2} $pdb->{appinfo}{fieldLabels}{phone3} $pdb->{appinfo}{fieldLabels}{phone4} $pdb->{appinfo}{fieldLabels}{phone5} $pdb->{appinfo}{fieldLabels}{phone6} $pdb->{appinfo}{fieldLabels}{phone7} $pdb->{appinfo}{fieldLabels}{phone8} $pdb->{appinfo}{fieldLabels}{address} $pdb->{appinfo}{fieldLabels}{city} $pdb->{appinfo}{fieldLabels}{state} $pdb->{appinfo}{fieldLabels}{zipCode} $pdb->{appinfo}{fieldLabels}{country} $pdb->{appinfo}{fieldLabels}{title} $pdb->{appinfo}{fieldLabels}{custom1} $pdb->{appinfo}{fieldLabels}{custom2} $pdb->{appinfo}{fieldLabels}{custom3} $pdb->{appinfo}{fieldLabels}{custom4} $pdb->{appinfo}{fieldLabels}{note} These are the names of the various fields in the address record. $pdb->{appinfo}{country} An integer: the code for the country for which these labels were designed. The country name is available as $Palm::Address::countries[$pdb->{appinfo}{country}]; $pdb->{appinfo}{misc} An integer. The least-significant bit is a flag that indicates whether the database should be sorted by company. The other bits are reserved. Sort block $pdb->{sort} This is a scalar, the raw data of the sort block. Records $record = $pdb->{records}[N]; $record->{fields}{name} $record->{fields}{firstName} $record->{fields}{company} $record->{fields}{phone1} $record->{fields}{phone2} $record->{fields}{phone3} $record->{fields}{phone4} $record->{fields}{phone5} $record->{fields}{address} $record->{fields}{city} $record->{fields}{state} $record->{fields}{zipCode} $record->{fields}{country} $record->{fields}{title} $record->{fields}{custom1} $record->{fields}{custom2} $record->{fields}{custom3} $record->{fields}{custom4} $record->{fields}{note} These are scalars, the values of the various address book fields. $record->{phoneLabel}{phone1} $record->{phoneLabel}{phone2} $record->{phoneLabel}{phone3} $record->{phoneLabel}{phone4} $record->{phoneLabel}{phone5} Most fields in an AddressBook record are straightforward: the "name" field always gives the person's last name. The "phoneN" fields, on the other hand, can mean different things in different records. There are five such fields in each record, each of which can take on one of eight different values: "Work", "Home", "Fax", "Other", "E-mail", "Main", "Pager" and "Mobile". The $record->{phoneLabel}{phone*} fields are integers. Each one is an index into @Palm::Address::phoneLabels, and indicates which particular type of phone number each of the $record->{phone*} fields represents. $record->{phoneLabel}{display} Like the phone* fields above, this is an index into @Palm::Address::phoneLabels. It indicates which of the phone* fields to display in the list view. $record->{phoneLabel}{reserved} I don't know what this is. METHODS
new $pdb = new Palm::Address; Create a new PDB, initialized with the various Palm::Address fields and an empty record list. Use this method if you're creating an Address PDB from scratch. new_Record $record = $pdb->new_Record; Creates a new Address record, with blank values for all of the fields. The AppInfo block will contain only an "Unfiled" category, with ID 0. "new_Record" does not add the new record to $pdb. For that, you want "$pdb->append_Record". SOURCE CONTROL
