Value in range from progress
|
|
|
|
Given a lower limit and an upper limit, we return the value within
|
|
that range as expressed by progress (usually a number from 0 to 1)
|
|
|
|
So progress = 0.5 would change
|
|
|
|
from -------- to
|
|
|
|
to
|
|
|
|
from ---- to
|
|
|
|
E.g. from = 10, to = 20, progress = 0.5 => 15
|
|
|
|
@param [number]: Lower limit of range
|
|
@param [number]: Upper limit of range
|
|
@param [number]: The progress between lower and upper limits expressed 0-1
|
|
@return [number]: Value as calculated from progress within range (not limited within range)
