ID:61001 In altfp_add_sub megafunction, the value of WIDTH_EXP parameter is <number>, but must be at least 8

CAUSE: You specified an illegal value for the WIDTH_EXP parameter of the altfp_add_sub megafunction. However, the value of the WIDTH_EXP parameter must be at least 8.

ACTION: Change the value of the WIDTH_EXP parameter so that the value of the parameter is greater than or equal to 8.
