The list of methods to do Double Number Equal are organized into topic(s).

Method

booleandoubleEqual(double d1, double d2)
Returns whether the two specified double value are equal. 
double absDiff = Math.abs(d1 - d2);
return absDiff < FP_EQUALITY_THRESHOLD;
booleandoubleEqual(double d1, double d2, double delta)
double Equal 
if (delta < 0) {
    throw new IllegalArgumentException("Delta for doubleEqual cannot be < 0: " + delta);
double diff = d1 - d2;
return ((diff >= 0) && (diff < delta)) || ((diff < 0) && (diff > -delta));
booleandoubleEqual(double v1, double v2)
double Equal 
return (Double.isNaN(v1) && Double.isNaN(v2)) || Math.abs(v1 - v2) < epsilon;
booleandoubleEquality(double v1, double v2, double epsilon)
a pseudo-equality check for doubles 
return Math.abs(v1 - v2) < epsilon;
booleandoubleEquals(double a, double b)
Implements the semantics of Double#equals(Object) for two primitive doubles. 
return Double.doubleToLongBits(a) == Double.doubleToLongBits(b);
booleandoubleEquals(double a, double b)
double Equals 
return doubleEquals(a, b, DEFAULT_EPSILON);
booleandoubleEquals(double a, double b)
Returns true if the two doubles are within a small epsilon of each other. 
return Math.abs(a - b) < epsilon;
booleandoubleEquals(double d1, double d2)
double Equals 
return Double.compare(d1, d2) == 0;
booleandoubleEquals(Double d1, Double d2)
Check if the two Double values are equal by checking that the absolute value between them is less than 0.01 
return Math.abs(d1 - d2) <= 0.01;
booleandoubleEquals(double d1, double d2, double epsilon)
double Equals 
return Math.abs(d1 - d2) <= epsilon;
