## FMOD(3)

```
```

### NAME[Toc][Back]

```     fmod, fmodf -- floating-point remainder functions
```

### LIBRARY[Toc][Back]

```     Math Library (libm, -lm)
```

### SYNOPSIS[Toc][Back]

```     #include <math.h>

double
fmod(double x, double y);

float
fmodf(float x, float y);
```

### DESCRIPTION[Toc][Back]

```     The fmod() and the fmodf() functions compute the floating-point remainder
of x/ y.
```

### RETURN VALUES[Toc][Back]

```     The fmod() and the fmodf() functions return the value x-i*y, for some
integer i such that, if y is non-zero, the result has the same sign as x
and magnitude less than the magnitude of y.  If y is zero, whether a
domain error occurs or the fmod() and the fmodf() function returns zero
is implementation-defined.
```

```     math(3)
```

### STANDARDS[Toc][Back]

```     The fmod() function conforms to ISO/IEC 9899:1990 (``ISO C89'').

FreeBSD 5.2.1			  May 2, 1991			 FreeBSD 5.2.1```
