Adjust Value Boundary Percentage
Convert the boundary of a percentage or value from one to another, using two old bounds and applying the new ones in the given formula:
Formula
newValue = (((oldValue - oldMinimum) * (newMaximum - newMinimum)) / (oldMaximum - oldMinimum)) + newMinimum
Example:
- Convert
x = 62from old boundary of 52-100 to be bound to 0-100.
x = (((62 - 52) * (100 - 0)) / (100 - 52)) + 0
JavaScript
/**
* @param int number The number to adjust.
* @param int oldMin The old minimum value.
* @param int oldMax The old maximum value.
* @param int newMin The new minimum value to convert to.
* @param int newMax The new maximum value to convert to.
*
* @returns int The original number converted to the new boundary.
*/
function convertValueToBoundary(number, oldMin, oldMax, newMin, newMax)
{
return (((number - oldMin) * (newMax - newMin)) / (oldMax - oldMin)) + newMin
}
Example
For instance, given the number 5 within a range of 0-10, we want to increase the numerical range to be between 0-100 instead.
convertValueToBoundary(5, 0, 10, 0, 100) // Output -> 50
