Iscalef() converts a floating-point input value to the specified floating-point range.

float Iscalef(float x, float in_min, float in_max, float out_min, float out_max)

void setup() {
  Serial.begin(115200);
}
 
void loop() {
  const float raw = (float)analogRead(A0);  // Read the raw analog value of the specified channel.
  const float pressureBar = Iscalef(raw, 0.0F, 32767.0F, 0.0F, 10.0F);  // Map a floating-point input to the specified floating-point range.
  if (pressureBar >= 0.0F && pressureBar <= 10.0F) Serial.println(pressureBar, 2);
  delay(100);
}

• All arguments and the return value of Iscale() have a range of -2147483648~2147483647.
• Out-of-range inputs are clamped to the nearest output endpoint.
• Both commands perform only linear range conversion. They do not replace sensor calibration or electrical protection.
