Use the Math.BigMul Method to Find Multiple Large Integers

System.Math provides the BigMul method for cases where you have to find the product of two large integer numerals that may result in a value that would cause an System.Overflow Exception. The BigMul method returns a long number, which avoids the overflow.

System.Int32 i = 245525352;
System.Int32 j = 245552352;
System.Int32 k = 0;

//This one will work
var result = System.Math.BigMul(i, j);
//This one will throw Arithmetic overflow exception
k = i * j;
