Quick Math Help with Normalized numbers

Ok, i have a normalised number (in the range 0 - 1) which represents a point along a line. Or a percentage.

How do i convert this into a number in the range 0.5 - 2, making it represent the same point/percentage along that scale?

i’m sure this is pretty basic math, but my brain seems to not be working today

Almost the same as the previous answer but a bit more reliable.
Your percentage value will be normalized in 0 … 1 range with this call:

float result = Mathf.Lerp(0.5, 2.0, yourPercentage);

float valueChange(float value,float newMin,float newMax){

return newMin + value * (newMax - newMin);
}
