analysis

Thanks Andrew, it works perfectly.

 I'm also interested to list all the variable corner temp iled i differential_psrr in a list and fprint them

 variable=list(
corner
temp
i
)

foreach(val variable
fprintf(out "%g\t"  val)

)

error mgs:
Error fprintf/sprintf: format spec. incompatible with data -40

Corner is a string, temp is decimal, and i is a floating number, how can i lump different outout togther?

How about:

foreach(val variable
  fprintf(out if(numberp(val) "%N\t" "%s\t") val)
)

Regards,

Andrew.

What is %N use for?

foreach(val variable
  fprintf(out if(numberp(val) "%N\t" "%s\t") val)
)

 that return: synatx error encountered in input

i tried using:

 foreach(val variable

  fprintf(out if(numberp(val) "%g\t%s\t") val)
)

 and that return: type template = "ptg"

I'm not sure what you did incorrectly, because the first form is entirely correct and valid for as long as I can remember in SKILL. I just cut and paste it, and it worked fine. For example:

variable='("hello" 4.2 27)
out=stdout
foreach(val variable
  fprintf(out if(numberp(val) "%N\t" "%s\t") val)
)

this worked perfectly. The "%N" (as covered in the documentation for fprintf/printf) is for displaying any kind of number (float or integer). What the code above does is either use %N or %s as the format depending on whether it's a number or not.

Your second code won't work because it either gives a format which has two format strings, but only one argument, or it returns nil (if not a number) which will give the type template error.

Kind Regards,

Andrew.

The script works fine after i tweak the variable values to be all float number. and use %g instead of %N.

Does it have to do with the version? I'm using version 5.1.0 

I tried the example in CIW,

) 

Here's the output

("hello" 4.2 27)
port:"*stdout*"
hello
*Error*  fprintf/sprintf: illegal format spec. -"%N\t"

 A bit of tweaking :

)  

 output as below

("hello" 4.2 27)
port:"*stdout*"
hello 4.2 2.7
("hello" 4.2 2.7)

Sorry, my mistake. It was "%n" that has been there for years, not "%N". %N uses a more compact notation. So you can either change the %N to %n, or use this code instead:

foreach(val variable
  fprintf(out "%s\t" if(numberp(val) aelEngNotation(val) val))
)

Depending on which looks the nicest to you!

Andrew.

Thanks andrew.

It works well now.

Hello Andrew,

 When using  foreach(val variable

  fprintf(out if(numberp(val) "%n\t" "%s\t") val)

)

 can i increase the number resolution?

There is output but it came out as 0.0000, the value i'm expecting is 2e-9 (for example)

The %n sequence means "use %d if an integer, or %f if a floating point number". In IC615 you can use %N which means "use %d if an integer, or %g if a floating point number". So %N would do what you want; similarly if you know the value is a flonum, you can just use %g. Or if you always want it in exponential format, you could use %e.

Regards,

Andrew.
