+# roundsdf
+
+> Round a single-precision floating-point number to the nearest value with `n` significant figures.
+
+
+
+## Usage
+
+```javascript
+var roundsdf = require( '@stdlib/math/base/special/roundsdf' );
+```
+
+#### roundsdf( x, n )
+
+Rounds a single-precision floating-point number to the nearest value with `n` significant figures.
+
+```javascript
+var v = roundsdf( 3.141592653589793, 3 );
+// returns 3.14
+
+v = roundsdf( 3.141592653589793, 1 );
+// returns 3.0
+
+v = roundsdf( 12368.0, 2 );
+// returns 12000.0
+
+v = roundsdf( -12368.0, 2 );
+// returns -12000.0
+```
+
+
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var uniform = require( '@stdlib/random/array/uniform' );
+var logEachMap = require( '@stdlib/console/log-each-map' );
+var roundsdf = require( '@stdlib/math/base/special/roundsdf' );
+
+var opts = {
+ 'dtype': 'float32'
+};
+
+var x = uniform( 100, -5000.0, 5000.0, opts );
+
+logEachMap( 'x: %0.4f. n: 3. rounded: %0.4f.', x, 3, roundsdf );
+```

+## C APIs
+
+
+
+
+
+
+
+
+
+
+
+### Usage
+
+```c
+#include "stdlib/math/base/special/roundsdf.h"
+```
+
+#### stdlib_base_roundsdf( x, n )
+
+Rounds a single-precision floating-point number to the nearest value with `n` significant figures
+
+```c
+float v = stdlib_base_roundsdf( 3.1415927f, 3 );
+// returns 3.14f
+```
+
+The function accepts the following arguments:
+
+- **x**: `[in] double` input value.
+- **n**: `[in] int32_t` number of significant figures.
+
+```c
+float stdlib_base_roundsdf( float x, int32_t n );
+```
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+### Examples
+
+```c
+#include "stdlib/math/base/special/roundsdf.h"
+#include
+#include
+
+int main( void ) {
+ const float x[] = { 3.143546f, -3.142635f, 0.0f, NAN };
+
+ float y;
+ int i;
+
+ for ( i = 0; i < 4; i++ ) {
+ y = stdlib_base_roundsdf( x[ i ], 2 );
+ printf( "roundsdf(%f) = %f\n", x[ i ], y );
+ }
