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 convert `float in_min` `float in_max` `float out_min` `float out_max`	`float`	Converts a floating-point input value to the specified floating-point range.

Example

void loop() {
  int32_t raw = (int32_t)analogRead(A0);
  int32_t percent = Iscale(raw, 0, 1023, 0, 100);
  float voltage = Iscalef((float)raw, 0.0F, 1023.0F, 0.0F, 5.0F);
 
  Serial.println(percent);
  Serial.println(voltage, 2);
}

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.
