Your numbers are fixed point not floating point. Fixed point means applying a fixed scaling to integer numbers. Most popular are binary (2^n) scaling factors. Number ranges and resolution can be different for x and y of a function and need to be defined according to your accuracy requirements.

By the way, do you actually mean divergent exp(t^2/l^2) or gauss function exp(-t^2/l^2)?
