Permissible Argument Ranges lists the permissible argument ranges for each of the specified mathematical functions. The word All signifies that all single-precision numbers—or double-precision numbers if the function is double-precision—are permitted. All is often modified in some obvious manner. If a function has more than one argument, the requirements for each are listed separated by commas (,). The notation (0,0) means that both the first and second arguments are 0 (zero).
