Issue with saving text file using sprintf

Hi,

I am using the below commad to write data file to text file.

Ideally I want my text file to saved as as 'data_0.5.txt', unfortunately now it is saved as 'data_0.500000.txt'. Essentialy I want to limit to one digits after the decimal point.

h=0.5
writetable(data,sprintf('data_%f.txt',w));

Hello,

To limit the number of digits after the decimal point to one in the filename, you should modify the sprintf format specifier from %f to %.1f. This will format the floating-point number to have only one digit after the decimal point. Here's how you can do it:

h = 0.5;
writetable(data, sprintf('data_%.1f.txt', h));

In this modified command, %.1f specifies that the floating-point number (h in this case) should be formatted with one digit after the decimal point.

Regards.
