What's the meaning of 1.000D+00

Dear experts, I use Score card to tally the enery deposition of various region. However, after the simulation, I found the results is expressed as 1.000D+00, I am a little confused about the express of xxxxD+xx, what is the difference of this expresssion with the Scientific notation (1.000E+00)

Dear Jia,

The “D” notation in Fortran means, that the number is a double precision (8 byte) floating point number, while the “E” only represents a 4 byte floating point number.


Dear David, I understand. Thank you very much.
