AreCloseWithTolerance(double, double)

Determines whether two double-precision floating-point numbers are approximately equal within a specified relative and absolute tolerance.

public static bool AreCloseWithTolerance(double a, double b)

Parameters

a double

The first double-precision floating-point number to compare.

b double

The second double-precision floating-point number to compare.

Returns

bool

true if the two numbers are approximately equal within the defined tolerances; otherwise, false.

Remarks

The comparison uses a relative tolerance of 1e-12 and an absolute tolerance of 1e-15. This ensures that the method accounts for both small differences in large numbers and significant differences in numbers close to zero.

AreCloseWithTolerance(float, float)

Returns true if the two single-precision floats are close enough to be considered equal, using both relative and absolute tolerance.

public static bool AreCloseWithTolerance(float a, float b)

Parameters

a float

First value to compare.

b float

Second value to compare.

Returns

bool

true if the values are close; otherwise, false.

Examples

AreCloseWithTolerance(1.0f, 1.000001f);     // true
AreCloseWithTolerance(0.0f, 1e-8f);         // false
AreCloseWithTolerance(float.NaN, float.NaN); // false
AreCloseWithTolerance(float.PositiveInfinity, float.PositiveInfinity); // true

Remarks

This method handles near-zero comparisons and large magnitudes by combining relative and absolute tolerances. It is symmetric with AreCloseWithTolerance(double, double).
