Function Documentation

are_almost_equal()

bool others::are_almost_equal	(	double	a,
		double	b,
		double	absolute_tolerance = 0.0001 )

Compare two floating point numbers with a certain tolerance. This is needed as with some values, the result (e.g.: -196.15) might be a bit lower (in this case, -196.499999...).

Parameters

a	the first number to compare
b	the second number to compare
tolerance	the tolerance to use when comparing the numbers

Returns

true if the numbers ARE equal within the given tolerance

false if the numbers are NOT equal within the given tolerance otherwise

    return std::abs(a - b) < absolute_tolerance;
}

kelvin_to_celsius()

double others::kelvin_to_celsius

(

double

temperature_in_k

)

Conversion from Kelvin to Celsius algorithm.

Parameters

number

the Celsius number that will be used to convert

Returns

the Kelvin number converted to Celsius
