The same with double (it is 64bit float). It prints as 32bit float today. Would be great to have it in Print class.

This is a workaround for example:

char buf[25];
double fff = 1.234567890123456e-23;
sprintf(buf,"%1.15e", fff);
Serial.print(buf);

does this help?

gcvt(double,int,char*);

use the int for precision. Example: 4 gives four numbers. 3.1248752 prints as 3.124
