Detailed Description

Comparison of real values.

Compares two reals if they are exactly numerically equal or not, i.e. equal:

\[ |\frac{a-b}{b}| < \epsilon \]

Example

Returns ´.false.´ in 5th element of isequal

vec1 = (/ 1., 2., 3., -999., 5., 6. /)
vec2 = (/ 1., 1., 3., -999., 10., 6. /)
isequal = equal(vec1, vec2)

Returns ´.true.´ in all elements of isequal

vec1 = (/ 1., 2., 3., -999., 5., 6. /)
vec2 = (/ 1., 1., 3., -999., 10., 6. /)
isequal = equal(vec1, vec2)

Returns ´.false.´ in 6th element of isequal

vec1 = (/ 1., 2., 3., -999., 5., nan /)
vec2 = (/ 1., 1., 3., -999., 10., nan /)
isequal = equal(vec1, vec2)

Parameters

[in]	real(sp/dp) :: a	First number to compare
[in]	real(sp/dp) :: b	Second number to compare

Return values

real(sp/dp) :: equal

\( a == b \) logically true or false
