near - Determine whether two values are roughly equal.
loadrt near [count=N|names=name1[,name2...]]
near.N (requires a floating-point thread)
near.N.in2 float in
near.N.out bit out
out is true if in1 and in2 are within a factor of scale (i.e., for in1 positive, in1/scale <= in2 <= in1*scale), OR if their absolute difference is no greater than difference (i.e., |in1-in2| <= difference). out is false otherwise.
float rw (default: 1)
near.N.difference float rw (default: 0)
