Bosses how to write ah, look at this to calculate much td and assume that td is not close, if it returns to assume that the step of td (every assumption of td is on the basis of a td + 0.0001), if the calculated Er Er is not similar with the assumption that would return to the step to assume that the Er (every assumed to be in the Er + 0.0001) on the basis of an Er,
The two loops should be how to write ah,
