There are two codes.

// (gps.location.lat(), 4),
// (gps.location.lng(), 4)

How to these values ​​to assign a variable float ? I need 4 digits after the decimal point.How to use?

Example:
float x=4,1234
float y=8,7812

Thanks.

That is nonsense. Why do you think that "(gps.location.lat(), 4)" means anything?

float lat = gps.location.lat();

I have no idea about lng...

I need 4 digits after the decimal point.

That is nonsense. The number of digits after a decimal point is something that matters ONLY when printing a value.

Very thanks .I find solution thanks to you .

example:

double x=gps.location.lat(); // gps.location.lat() is double type, latitude coordinate;
double y=gps.location.lng(); //gps.location.lng() is double type,longtitude coordinate;
Serial.print(x,4);
Serial.print(y,4);

Example:
float x=4,1234
float y=8,7812

Remember, you have to be American and use decimal points instead. Like this:

Example:
float x=4.1234
float y=8.7812
