Detailed Description

A point of a membership function = a pair (REALVAL,FUZZYVAL)

All the functions that assign a value to the Fuzzy value (constructor and Set(REALVAL x, FUZZYVAL y) ) truncate the value so it always lies in the range [0:1]

Operator needed for sorting, sorts point according to Ox axis ('real' axis)

References _x.

bool slifis::FPOINT::operator==

(

const FPOINT &

fpt

)

const

Returns true if point fpt and current point are identical, up to a certain value (see "more")

This involves doing floating-point comparison.

• For the "real" axis, this is done with the macro FLOAT_ARE_EQUAL
• For fuzzy axis, as these values are guarenteed to lie in the range [0:1], absolute comparison is done using constant SLIFIS_EPSILON_FUZZY.

Was inlined up to release 0.5.1, but moved over here to keep macro FLOAT_ARE_EQUAL private (symbol not exported)
