| fea681da | 22 | .SH DESCRIPTION |
| c13182ef | 23 | The call |
| 3b2049e5 | 24 | .I clog10(z) |
| e17f9d28 | 25 | is equivalent to |
| 2c81ad3b | 26 | .IR clog(z)/log(10) . |
| c13182ef | 27 | The other functions perform the same task for |
| 3b2049e5 | 28 | .I float |
| c13182ef | 29 | and |
| 3b2049e5 MK |
30 | .IR "long double" . |

| 34 | close to zero will cause an overflow. | |
