ID:61002 In altfp_add_sub megafunction, the value of WIDTH_MAN is <number>, but must be at least 23

CAUSE: You specified an illegal value for the WIDTH_MAN parameter of the altfp_add_sub megafunction. However, the value of the WIDTH_EXP parameter must be at least 23. This error usually occurs when you instantiate a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager .

ACTION: Change the value of the WIDTH_MAN parameter so that the value of the parameter is greater than or equal to 23.
