Java Utililty Methods Float Number Equal

List of utility methods to do Float Number Equal

Description

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

boolean areFloatsEqual(float f1, float f2)
used to compare two floats which are tested for having (almost) the same value

return areFloatsEqual(f1, f2, 0.001F);

return (Math.abs(f1 - f2) < 0.0000001);

boolean areFloatsEqual(Float one, Float two)
Checks if two floats are equal - handles nulls

boolean nullDiff = one == null ^ two == null;
boolean valueDiff = one != null && two != null && !one.equals(two);
return !nullDiff && !valueDiff;

boolean equal(float val1, float val2)
Checks if two floats are equal based on identity.

return Float.floatToIntBits(val1) == Float.floatToIntBits(val2);

return Math.abs(f1 - f2) < 0.0000001f;

return (Math.abs(a - b) < epsilon);

boolean floatEqual(float f1, float f2)
Returns whether the two specified float value are equal.

float absDiff = Math.abs(f1 - f2);
return absDiff < FP_EQUALITY_THRESHOLD;

boolean floatEquals(float a, float b)
Implements the semantics of Float#equals(Object) for two primitive floats.

return Float.floatToIntBits(a) == Float.floatToIntBits(b);

return Math.abs(x - y) < DELTA;
