The boost::math::gcd function template returns the greatest common (nonnegative)
|
|
divisor of the two integers passed to it. The boost::math::lcm function template
|
|
returns the least common (nonnegative) multiple of the two integers passed
|
|
to it. The function templates are parameterized on the function arguments'
|
|
IntegerType, which is also the return type. Internally, these function templates
|
|
use an object of the corresponding version of the gcd_evaluator and lcm_evaluator
|
|
class templates, respectively.
