FUNCTIONS

sci2dec($sci) => $dec
Convert scientific notation number to decimal number.
Note that if you are sure that your number is not too large or small, you can just let Perl convert it for you:
"1.2e-4"+0 # 0.00012
1*"1.2e8" # 120000000
but:
"1.2e-5"+0 # => 1.2e-5
1*"1.2e20" # 1.2e+20
FAQ

To convert to scientific notation, you can use sprintf()
with the %e
