max_diff	is the maximum absolute difference (allows to take care of the near-zero area, where relative difference methods cannot really work).
max_ulps	is the 'maximum number of floats + 1' allowed between a and b to consider them equal.

◆ ulp_diff_ff()

MINLINE uint ulp_diff_ff	(	float	a,
		float	b )

Computes the distance between two floats in ulps.

In other words, returns zero if the floats are exactly equal, and otherwise returns 1 plus the number of (unique) representable floats between a and b on the number line.

Notes:

The order of a and b doesn't matter. The returned value is the absolute difference.
Unlike many ulp difference functions, this function handles the difference between positive and negative floats in a meaningful way. It returns the number (plus 1) of representable floats between those two values as they would be arranged on a number line.
Zero and negative zero are not considered unique from each other. They are counted together as a single float in the difference.
NaNs are not handled meaningfully. If either number is NaN, this function returns uint max (0xffffffff).
