Visualize Arduino fscale mapping function

Code:

      function fscale(originalMin, originalMax, newBegin, newEnd, inputValue, curve) {
        let OriginalRange = 0;
        let NewRange = 0;
        let zeroRefCurVal = 0;
        let normalizedCurVal = 0;
        let rangedValue = 0;
        let invFlag = 0;
      
      
        // condition curve parameter
        // limit range
      
        if (curve > 10) curve = 10;
        if (curve < -10) curve = -10;
      
        curve = (curve * -.1); // - invert and scale - this seems more intuitive - postive numbers give more weight to high end on output 
        curve = Math.pow(10, curve); // convert linear scale into lograthimic exponent for other pow function
      
        // Check for out of range inputValues
        if (inputValue < originalMin) {
          inputValue = originalMin;
        }
        if (inputValue > originalMax) {
          inputValue = originalMax;
        }
      
        // Zero Refference the values
        OriginalRange = originalMax - originalMin;
      
        if (newEnd > newBegin) {
          NewRange = newEnd - newBegin;
        } else {
          NewRange = newBegin - newEnd;
          invFlag = 1;
        }
      
        zeroRefCurVal = inputValue - originalMin;
        normalizedCurVal = zeroRefCurVal / OriginalRange; // normalize to 0 - 1 float
      
        // Check for originalMin > originalMax  - the math for all other cases i.e. negative numbers seems to work out fine 
        if (originalMin > originalMax) {
          return 0;
        }
      
        if (invFlag == 0) {
          rangedValue = (Math.pow(normalizedCurVal, curve) * NewRange) + newBegin;
      
        } else // invert the ranges
        {
          rangedValue = newBegin - (Math.pow(normalizedCurVal, curve) * NewRange);
        }
        return rangedValue;
      }
