| fea681da | 19 | .SH DESCRIPTION |
| c13182ef | 20 | The call |
| 3b2049e5 | 21 | .I clog10(z) |
| e17f9d28 | 22 | is equivalent to |
| 2c81ad3b | 23 | .IR clog(z)/log(10) . |
| c13182ef | 24 | The other functions perform the same task for |
| 3b2049e5 | 25 | .I float |
| c13182ef | 26 | and |
| 3b2049e5 MK |
27 | .IR "long double" . |

29 | Note that |
| 30 | .I z | |
| 31 | close to zero will cause an overflow. | |
