+# ceilnf
+
+> Round a numeric value to the nearest multiple of 10^n toward positive infinity.
+
+<section class="usage">
+
+## Usage
+
+```javascript
+var ceilnf = require( '@stdlib/math/base/special/ceilnf' );
+```
+
+#### ceilnf( x, n )
+
+Rounds a `numeric` value to the nearest multiple of `10^n` toward positive infinity.
+
+```javascript
+// Round a value to 2 decimal places:
+var v = ceilnf( 3.141592653589793, -2 );
+// returns 3.15
+
+// If n = 0, `ceiln` behaves like `ceil`:
+v = ceilnf( 3.141592653589793, 0 );
+// returns 4.0
+
+// Round a value to the nearest thousand:
+v = ceilnf( 12368.0, 3 );
+// returns 13000.0
+```

+
+## 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 = ceilnf( x, -16 );
+    // returns 0.3000000000000001
+    ```

+### Usage
+
+```c
+#include "stdlib/math/base/special/ceilnf.h"
+```
+
+#### stdlib_base_ceilnf( x, n )
+
+Rounds a single-precision floating-point number to the nearest multiple of `10^n` toward positive infinity.
+
+```c
+// Round a value to 2 decimal places:
+float y = stdlib_base_ceilnf( 3.141592653589793f, -2f );
+// returns 3.15f
+
+// If n = 0, `ceilnf` behaves like `ceil`:
+float y = stdlib_base_ceilnf( 3.141592653589793f, 0f );
+// returns 4.0f
+
+// Round a value to the nearest thousand:
+float y = stdlib_base_ceilnf( 12368.0f, 3f );
+// returns 13000.0f
+```
+
+The function accepts the following arguments:
+
+-   **x**: `[in] float` input value.
+-   **n**: `[in] int32_t` integer power of 10.
+
+```c
+float stdlib_base_ceilnf( const float x, const int32_t n );
+```
