Description
Compares the variable on the left with the value or variable on the right of the operator. Returns true when the operand on the left is less (smaller) than the operand on the right. Please note that you may compare variables of different data types, but that could generate unpredictable results, it is therefore recommended to compare variables of the same data type including the signed/unsigned type.
Syntax
x < y; // is true if x is smaller than y and it is false if x is equal or bigger than y
Parameter Values
- x: variable. Allowed data types: int, float, double, byte, short, long.
- y: variable or constant. Allowed data types: int, float, double, byte, short, long.
Example Code
void setup() {
Serial.begin(9600);
int x = 1;
int y = 2;
if (x < y) // tests if x is less (smaller) than y
Serial.println("x is less than y");
}
void loop() {
}
The result on Serial Monitor:
COM6
x is less than y
Autoscroll
Clear output
9600 baud
