float with 3 digits after the point precision

Question

How can i can calaulate this in c? :

float x = 5;
float y = 4.999

float z = x-y; // 0.001000

Now i want z to be exactly 3 digits after the point, so that z will be = 0.001.
I don't need to print z, i just need to initialize it with 0.001.

@user3729959 Please read the answer of the linked question. They are not about printing, they are about representation of values in type float. — Werner Henze, Nov 12 '14 at 09:36
there's no way to do that unless you're using a decimal float type — phuclv, Nov 12 '14 at 09:46

Use the integer datatype and transform all numbers to a multiply of 1000

int x = 5000
int y = 4999

int z = x-y // 1
