+# roundn
+
+> Round a double-precision floating-point number to the nearest multiple of 10^n.
+
+
+
+## Usage
+
+```javascript
+var roundn = require( '@stdlib/math/base/special/roundn' );
+```
+
+#### roundn( x, n )
+
+Rounds a double-precision floating-point number to the nearest multiple of `10^n`.
+
+```javascript
+// Round a value to 2 decimal places:
+var v = roundn( 3.141592653589793, -2 );
+// returns 3.14
+
+// If n = 0, `roundn` behaves like `round`:
+v = roundn( 3.141592653589793, 0 );
+// returns 3.0
+
+// Round a value to the nearest thousand:
+v = roundn( 12368.0, 3 );
+// returns 12000.0
+```
+
+
+
+
+
+
+
+## Notes
+
+- When operating on [floating-point numbers][ieee754] in bases other than `2`, rounding to specified digits can be **inexact**. For example,
+
+ ```javascript
+ var x = 0.2 + 0.1;
+ // returns 0.30000000000000004
+
+ // Should round to 0.3...
+ var v = roundn( x, -16 );
+ // returns 0.3000000000000001
+ ```
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var randu = require( '@stdlib/random/base/randu' );
+var roundn = require( '@stdlib/math/base/special/roundn' );
+
+var x;
+var n;
+var v;
+var i;
+
+for ( i = 0; i < 100; i++ ) {
+ x = (randu()*100.0) - 50.0;
+ n = roundn( randu()*5.0, 0 );
+ v = roundn( x, -n );
+ console.log( 'x: %d. Number of decimals: %d. Rounded: %d.', x, n, v );
+}
+```

+## C APIs
+
+
+
+
+
+
+
+
+
+
+
+### Usage
+
+```c
+#include "stdlib/math/base/special/roundn.h"
+```
+
+#### stdlib_base_roundn( x, n )
+
+Rounds a double-precision floating-point number to the nearest multiple of `10^n`.
+
+```c
+double y = stdlib_base_roundn( 3.14, -2 );
+// returns 3.14
+```
+
+The function accepts the following arguments:
+
+- **x**: `[in] double` input value.
+- **n**: `[in] int32_t` integer power of 10.
+
+```c
+double stdlib_base_roundn( const double x, const int32_t n );
+```
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+### Examples
+
+```c
+#include "stdlib/math/base/special/roundn.h"
+#include
+
+int main( void ) {
+ const double x[] = { 3.14, -3.14, 0.0, 0.0/0.0 };
+
+ double y;
+ int i;
+ for ( i = 0; i < 4; i++ ) {
+ y = stdlib_base_roundn( x[ i ], -2 );
+ printf( "roundn(%lf) = %lf\n", x[ i ], y );
+ }
+}
