| 41 | .In math.h |
| 42 | .Ft double |
| 43 | .Fn fmax "double x" "double y" |
| 44 | .Ft float |
| 45 | .Fn fmaxf "float x" "float y" |
| 46 | .Ft "long double" |

| 54 | .Sh DESCRIPTION |
| 55 | The |
| 56 | .Fn fmax , |
| 57 | .Fn fmaxf , |
| 58 | and |
| 59 | .Fn fmaxl |
| 60 | functions return the larger of |
| 61 | .Fa x |
| 62 | and |
| 63 | .Fa y , |
| 64 | and likewise, the |
| 65 | .Fn fmin , |
| 66 | .Fn fminf , |
| 67 | and |
| 68 | .Fn fminl |
| 69 | functions return the smaller of |
| 70 | .Fa x |
| 71 | and |
| 72 | .Fa y . |
| 73 | They treat |
| 74 | .Li +0.0 |
| 75 | as being larger than |
| 76 | .Li -0.0 . |
| 77 | If one argument is an \*(Na, then the other argument is returned. |
| 78 | If both arguments are \*(Nas, then the result is an \*(Na. |
| 79 | These routines do not raise any floating-point exceptions. |
