"dtostrf" function available for MKR GSM 1400

I have been working on a super simple sketch to prove a concept for how I can get the float values for latitude and longitude, then convert them into a char array so I can output them to a website.

#include<stdlib.h>

void setup() {
  Serial.begin(115200);
  
  float latitude = 47.2035;
  float longitude = 15.3268;
  char latBuffer[50];
  char longBuffer[50];
  char fullBuffer[100];
  
  dtostrf(latitude, 0, 7, latBuffer);
  dtostrf(longitude, 0, 7, longBuffer);

  sprintf_P(fullBuffer, PSTR("Latitude: %s;Longitude: %s"), latBuffer, longBuffer);
  Serial.println(fullBuffer);    // Prints: "Latitude: 47.2035;Longitude: 15.3268"
}

void loop(){}

Whilst this sketch does compile if I set the board type to be Arduino Uno, when I change it to MKR GSM 1400 it fails to compile with the error:

float-to-char-array:12: error: 'dtostrf' was not declared in this scope

   dtostrf(latitude, 0, 7, latBuffer);

                                    ^

exit status 1
'dtostrf' was not declared in this scope

So I am just wondering if there are plans to have the "dtostrf" added to the standard library availble to the MKR GSM 1400.

Thanks

Add this line to your sketch:

#include <avr/dtostrf.h>

Awesome thanks for helping with that, that'll help in passing lat and long into a char array. That's fixed up the error I was getting at compile time.

Cheers
