Format a number in scientific notation

Surprisingly, neither ASP nor PHP seem to have a built-in way of formatting a number in scientific notation. Today we're going to change that.

ASP

1. function formatScientific(someFloat)
2.     dim power
4.     power = (someFloat mod 10) - 1
5.     formatScientific = cStr(cDbl(someFloat) / 10^power) & "e" & cStr(power)
6. end function

PHP

1. function formatScientific($someFloat)
2. {
3.     $power = ($someFloat % 10) - 1;
4.     return ($someFloat / pow(10, $power)) . "e" . $power;
5. }
