The Chapel counterpart is writef(), see:
https://chapel-lang.org/docs/modules/standard/IO/FormattedIO.html#FormattedIO.writef
The formatting for reals is discussed here:
https://chapel-lang.org/docs/modules/standard/IO/FormattedIO.html#real-conversions
If "%er" does not work when you pass an int to it, cast your int to real, like
writef("%er", bignum:real);
BTW this makes for a perfect StackOverflow question with a "chapel" tag. Would
you mind posting it there so we can respond?

Subject: [Chapel-developers] writeln formatting
Greetings,
Simple question, taking your example for factorials, how would I need to change
writeln to print out the correct value for say 150! in exponential form, in C
would be printf("%le", bignum);
Or you could point me to where this is in the documentation?
Regards,
-Tyler
proc factorial(x: int) : int{
if x < 0 then
halt("factorial -- Sorry, this is not the gamma procedure!");
return if x == 0 then 1 else x * factorial(x-1);}writeln("A simple
procedure");writeln("150! is ", factorial(150));writeln();
