SUMMARY

The discussion focuses on converting a double to a string in MATLAB while preserving the last digit, specifically the trailing zero. When using the command num2str(numnum), the conversion truncates the number, omitting the zero. To retain the trailing zero, users should specify the format as a floating point number using num2str(numnum, '%3.3f'). Additional formatting options are available in the MATLAB Help manual for num2str.

PREREQUISITES
  • Familiarity with MATLAB programming language
  • Understanding of data types, specifically doubles and strings
  • Knowledge of formatting options in MATLAB
  • Access to MATLAB Help documentation
NEXT STEPS
  • Explore MATLAB's num2str formatting options in detail
  • Learn about other data type conversions in MATLAB
  • Investigate the use of scientific notation in MATLAB
  • Review best practices for handling floating-point precision in MATLAB
USEFUL FOR

MATLAB programmers, data analysts, and anyone needing to convert numerical data types while maintaining formatting integrity.

Hi all,
I am converting a double to a string. But in the following case:
-----------
format long
numnum=546.790;
num=num2str(numnum)
length(num)
---------------
when 'numnum' is converted to a string, the command truncates the number by leaving off the last digit, the zero. Is there a way to keep the zero on there when converting to a string?

Yes, specify the format as a floating point number
num2str(numnum,'%3.3f')
or use one of the other formats (scientific notation, etc.) listed in the Help manual. Check the Help entry for num2str and you'll see a clickable link to the format list.
