print with format

[Luis Isaac Ramos Garcia]

  Dear liters;

   When using the print function to save some numeric data to a file, is
it possible to save those numbers with some numeric format; for example
if I would like to save the sin(3.5)=-0.350783227, but only three
significant digits sin(3.5)=-0.351; Is there any way do this in macro
language.

    Thanks in advance,

Hi,

You can get some control over the format using the d2s() macro  
function.  See http://rsb.info.nih.gov/ij/developer/macro/functions.html#D

//sin(3.5)=-0.350783227
print(d2s(sin(3.5), -10));

Cheers,
Ben

See the d2s() function:
