+## Usage
+
+```javascript
+var scalar2array = require( '@stdlib/array/from-scalar' );
+```
+
+#### scalar2array( value\[, dtype] )
+
+Returns a single-element array containing a provided scalar value.
+
+```javascript
+var x = scalar2array( 3.0 );
+// returns <Float64Array>[ 3.0 ]
+```
+
+If not provided a `dtype` argument and `value`
+
+-   is a `number`, the default [data type][@stdlib/array/dtypes] is the [default][@stdlib/array/defaults] real-valued floating-point data type.
+-   is a complex number object of a known data type, the data type is the same as the provided value.
+-   is a complex number object of an unknown data type, the default [data type][@stdlib/array/dtypes] is the [default][@stdlib/array/defaults] complex-valued floating-point data type.
+-   is any other value type, the default [data type][@stdlib/array/dtypes] is `'generic'`.
+
+To explicitly specify the [data type][@stdlib/array/dtypes] of the returned array, provide a `dtype` argument.
+
+```javascript
+var x = scalar2array( 3.0, 'float32' );
+// returns <Float32Array>[ 3.0 ]
+```

+
+## Notes
+
+-   If `value` is a number and the `dtype` argument is a complex [data type][@stdlib/array/dtypes], the function returns a complex number array containing a complex number whose real component equals the provided scalar `value` and whose imaginary component is zero.
+-   The function does **not** guard against precision loss when `value` is a number and the `dtype` argument is an integer [data type][@stdlib/array/dtypes].
