Converting Float to SN notation

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Whats the easiest way to convert floats to scientific notation? For example I would like to convert:

3447.0973333 to 
3.4470973333e+003

0.5 to
5.0000000000e-001

Thanks!

Check out the docs for sprintf (or perldoc -f sprintf), as a quick example it could be done like: `@nums = qw(3447.097333 0.5); print sprintf("%e", $_), "\n" for @nums`	[reply] [d/l]

Thanks...that works great...I just had to adjust the precision: print sprintf("%.10e", $_), "\n" for @nums and it works perfectly. Thanks again	[reply]
