I'm not sure if this is exactly what you were asking, but to read a float
value into a string in exponential form you can simply use:

IDL> a=3.567
IDL> b=strtrim(string(a,format='(e11.4)'),2)
IDL> print,b
3.5670e+00
IDL> help,b
B STRING = '3.5670e+00'

If you actually want to force the numbers themselves to appear in this
format whatever their value then I'm afraid I can't help, sorry...

All the best,

Tim Hammond.
