Hi,
I am working with precise numbers. I have noticed that the abs function, does not work correctly.
void setup() {
Serial.begin(115200);
}
void loop() {
double number = 0.000000029166328080224515062468;
double number2 = abs(number);
Serial.println(number, 30);
Serial.println(number2, 30);
delay(1000);
}
Outputs
0.000000029166328080224520391539
0.000000000000000000000000000000
Is it possible that double has 64 bit, and the abs function is good only for 32 bit numbers?
Thanks!
