SUMMARY

The discussion clarifies that in the output of the Gaussian program, the notation "D" represents "times ten to the" and indicates double precision. The user, Mr. nicksauce, confirms this interpretation while also prompting a comparison between "D" and "E" in scientific notation. The distinction is that "E" is commonly used in programming and scientific contexts to denote exponentiation, while "D" specifically refers to double precision in Gaussian outputs.

PREREQUISITES
  • Understanding of Gaussian program output formats
  • Familiarity with scientific notation in programming
  • Knowledge of double precision data types
  • Basic concepts of numerical analysis
NEXT STEPS
  • Research the differences between double precision and single precision in numerical computing
  • Explore the Gaussian program documentation for output interpretation
  • Learn about scientific notation in programming languages like Python and C++
  • Investigate the implications of precision in computational results
USEFUL FOR

Researchers, computational chemists, and anyone utilizing the Gaussian program for quantum chemistry calculations will benefit from this discussion.

in output result of Gaussian program I find Numbers such as

0.0323424 D-2
what meaning D here
 
Mathematics news on Phys.org
Presumably D = (times ten to the), and it signifies double precision.
 
thanks so much Mr nicksauce but what the diffrent between D and E
