| 4 | # that do not use floating point. If a program uses floating point then the

| 7 | # '_f_print' and 'strtod' from the library libd.a. Otherwise two dummy
|

| 8 | # routines are found in libc.a. (The printf and scanf need floating point
|

| 9 | # for the %f formats, whether you use them or not.)
