example pic
float a = 20;

float b = 80;

float c = lerp(a, b, .2);

float d = lerp(a, b, .5);

float e = lerp(a, b, .8);


vertex(a, 50);

vertex(b, 50);

vertex(c, 50);

vertex(d, 50);

vertex(e, 50);

example pic
int x1 = 15;

int y1 = 10;

int x2 = 80;

int y2 = 90;

line(x1, y1, x2, y2);

for(int i=0; i<=10; i++) {

  float x = lerp(x1, x2, i/10.0) + 10;

  float y = lerp(y1, y2, i/10.0);

  point(x, y);

Description Calculates a number between two numbers at a specific increment. The amt parameter is the amount to interpolate between the two values where 0.0 equal to the first point, 0.1 is very near the first point, 0.5 is half-way in between, etc. The lerp function is convenient for creating motion along a straight path and for drawing dotted lines.
lerp(value1, value2, amt)
value1 float or int: first value
value2 float or int: second value
amt float: between 0.0 and 1.0
