improvement request:
please enable sprintf() for float/double, like it's possible in Arduino ARM core

char* str[100];
// not possible for AVR and nodeMCU but possible for Arduino ARM core
sprintf(s, "floats: %4.2f %+.0e %E \n", 3.1416, 3.1416, 3.1416); 

[igrr]

See #1179, this feature is available in 2.4.0-rc1.

not possible in Arduino IDE 1.8.2 feat. esp8266 board manager
when is it automatically available via Arduino IDE?

[tofrnr]

this program still doesn't work as expected - when and how will it be fixed?

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
}

void loop() {
  // put your main code here, to run repeatedly:
  char sbuf[100];
  static int n;
  
  sprintf(sbuf, "%3d %10.8f", n++, PI);
  Serial.println(sbuf);
  delay(1000);
}
