Manual
gmp_gcdext(
GMP|int|string$num1,
GMP|int|string$num2 ): array
Calculates g, s, and t, such that a*s + b*t = g = gcd(a,b), where gcd is the greatest common divisor. Returns an array with respective elements g, s and t.
This function can be used to solve linear Diophantine equations in two variables. These are equations that allow only integer solutions and have the form: a*x + b*y = c. For more information, go to the "Diophantine Equation" page at MathWorld
Parameters
- num1
-
A GMP object, an int or a numeric string.
- num2
-
A GMP object, an int or a numeric string.
Return Values
An array of GMP numbers.
