+# truncbf
+
+> Round a [single-precision floating-point number][ieee754] toward zero to `n` digits in base `b`.
+
+
+
+## Usage
+
+```javascript
+var truncbf = require( '@stdlib/math/base/special/truncbf' );
+```
+
+#### truncbf( x, n, b )
+
+Rounds a [single-precision floating-point number][ieee754] toward zero to `n` digits in base `b`.
+
+```javascript
+var v = truncbf( 3.14159, 2, 10 );
+// returns 3.140000104904175
+
+v = truncbf( 3.14159, 3, 10 );
+// returns 3.1410000324249268
+
+v = truncbf( 15.0, -1, 10 );
+// returns 10.0
+
+v = truncbf( -3.14159, 2, 10 );
+// returns -3.140000104904175
+```
+
+If provided `NaN` or a `base` of `0`, the function returns `NaN`.
+
+```javascript
+var v = truncbf( NaN, 2, 10 );
+// returns NaN
+
+v = truncbf( 3.14, 2, 0 );
+// returns NaN
+```
+
+If provided `x = ±0` or `x = ±infinity`, the function returns `x`.
+
+```javascript
+var PINF = require( '@stdlib/constants/float32/pinf' );
+var NINF = require( '@stdlib/constants/float32/ninf' );
+
+var v = truncbf( 0.0, 2, 10 );
+// returns 0.0
+
+v = truncbf( -0.0, 2, 10 );
+// returns -0.0
+
+v = truncbf( PINF, 2, 10 );
+// returns Infinity
+
+v = truncbf( NINF, 2, 10 );
+// returns -Infinity
+```
+
+
+
+
+
+
+
+## Notes
+
+- This function is the [single-precision floating-point][ieee754] equivalent of [`truncb`][@stdlib/math/base/special/truncb].
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var randu = require( '@stdlib/random/base/randu' );
+var truncbf = require( '@stdlib/math/base/special/truncbf' );
+
+var x;
+var i;
+
+for ( i = 0; i < 100; i++ ) {
+ x = (randu() * 100.0) - 50.0;
+ console.log( 'truncbf(%d, 2, 10) = %d', x, truncbf( x, 2, 10 ) );
+}
+```

+## C APIs
+
+
+
+
+
+
+
+
+
+
+
+### Usage
+
+```c
+#include "stdlib/math/base/special/truncbf.h"
+```
+
+#### stdlib_base_truncbf( x, n, b )
+
+Rounds a [single-precision floating-point number][ieee754] toward zero to `n` digits in base `b`.
+
+```c
+float y = stdlib_base_truncbf( 3.14159f, 2, 10 );
+// returns 3.14f
+```
+
+The function accepts the following arguments:
+
+- **x**: `[in] float` input value.
+- **n**: `[in] int32_t` number of digits.
+- **b**: `[in] int32_t` base.
+
+```c
+float stdlib_base_truncbf( const float x, const int32_t n, const int32_t b );
+```
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+### Examples
+
+```c
+#include "stdlib/math/base/special/truncbf.h"
+#include
+
+int main( void ) {
+ const float x[] = { 3.14159f, -3.14159f, 15.0f, -15.0f };
+ const int32_t n[] = { 2, 3, -1, 0 };
+ const int32_t b = 10;
+
+ float y;
+ int i;
+ for ( i = 0; i < 4; i++ ) {
+ y = stdlib_base_truncbf( x[i], n[i], b );
+ printf( "truncbf(%f, %d, %d) = %f\n", x[i], n[i], b, y );
+ }
+}
