#!/usr/bin/perl
printf("The number in scientific notation is %e\n", 125.55);
Gives The number in scientific notation is 1.255500e+002
I test to enter the result you are looking for as
perl -42 de now ju can test single line of Perl kode
heter i enter print 1.255500e+02
( CTRL-Z) takes you out, (att least in WIndows version of PERL)
You can read more about formating data in this link
