+# isProbabilityf
+
+> Test if a single-precision floating-point number is a probability.
+
+
+
+## Usage
+
+```javascript
+var isProbabilityf = require( '@stdlib/math/base/assert/is-probabilityf' );
+```
+
+#### isProbabilityf( x )
+
+Tests if a single-precision floating-point number is a probability.
+
+```javascript
+var bool = isProbabilityf( 0.5 );
+// returns true
+
+bool = isProbabilityf( 3.14 );
+// returns false
+
+bool = isProbabilityf( NaN );
+// returns false
+```
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var uniform = require( '@stdlib/random/array/uniform' );
+var isProbabilityf = require( '@stdlib/math/base/assert/is-probabilityf' );
+
+var bool;
+var opts;
+var x;
+var i;
+
+opts = {
+ 'dtype': 'float32'
+};
+x = uniform( 100, -1.0, 1.0, opts );
+
+for ( i = 0; i < 100; i++ ) {
+ bool = isProbabilityf( x[ i ] );
+ console.log( '%d is %s', x[ i ], ( bool ) ? 'a probability' : 'not a probability' );
+}
+```

+
+
+
+## C APIs
+
+
+
+
+
+
+
+
+
+
+
+### Usage
+
+```c
+#include "stdlib/math/base/assert/is_probabilityf.h"
+```
+
+#### stdlib_base_is_probabilityf( x )
+
+Tests if a single-precision floating-point number is a probability.
+
+```c
+bool out = stdlib_base_is_probabilityf( 0.5f );
+// returns true
+
+out = stdlib_base_is_probabilityf( 3.14f );
+// returns false
+```
+
+The function accepts the following arguments:
+
+- **x**: `[in] float` input value.
+
+```c
+bool stdlib_base_is_probabilityf( const float x );
+```
+
+
+
+
+
+
+
+

+### Examples
+
+```c
+#include "stdlib/math/base/assert/is_probabilityf.h"
+#include
+#include
+#include
+
+int main( void ) {
+ float x;
+ bool v;
+ int i;
+
+ for ( i = 0; i < 100; i++ ) {
+ x = ( ( (float)rand() / (float)RAND_MAX ) * 2.0f ) - 1.0f;
