Thank you all, for your help.

format short g is ok.

is it possible to write the variables to text file in the format of short g with save command?
(short g: Best of fixed or floating point, with 4 digits after the decimal point. For example, 3.1416.)

I mean writing the values

0.0000000e+000 0.0000000e+000 -3.0000000e+002 5.0000000e+003

to the text file like
0 0 -300 5000

thank you

You can use the '%g' format in s/fprintf() functions for chosen field
width/precision.

You're at the mercy of the rt i/o library (essentially C Standard rules)
for what the actual form of any particular value will be converted to.
