Sir,<br /><br />In case of COBOL language, if we want to raise the power e.g. we need to find out 2 raise to power 2 is how much.......means square of 2,<br /><br />We can use<br /><br />COMPUTE C = 2 ** 2.<br /><br />this will work and after execution of this statement C will contain 4.<br /><br />but if I will raise the power by decimal number, it wont work....e.g.<br /><br />COMPUTE C = 4 ** (0.5).<br /><br />but after execution of this statement C should contain 2....... but I am getting error.......<br /><br />Kindly help me<br /><br />Ketaki
