Iscalef()
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)
Commands
| Command | Arguments | Return Value | Operation |
|---|---|---|---|
Iscalef(x, in_min, in_max, out_min, out_max) | float x — Input value to convertfloat in_minfloat in_maxfloat out_minfloat out_max | float | Converts a floating-point input value to the specified floating-point range. |
Example
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); }
Precautions
- 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.
