a simple math question

hi there:

i got a math operation question i wonder if any can tell me what the technical name for it and the best way to code it. i watn to wfite a code to describe the relationship between two variables x, y.

when x = 1, y = 100
when x = 2, y = 50
when x = 4, y = 25
when x = 0.5, y =200
when x = 0.25, y = 400

basically, when x gets larger, y becomes smaller, x gets smaller, y becomes larger.

what's the technical name for this operation? what's the best way to code this?

cheers

Code:

float x, y;

printf("Enter value of x: ");
scanf("%f", &x);

printf("y = %f\n", 100 / x);

Does that explain?
