Compute the cardinal sine of a number.

The normalized cardinal sine function is defined as

for any real number `x`

.

```
npm install @stdlib/math-base-special-sinc
```

```
var sinc = require( '@stdlib/math-base-special-sinc' );
```

Computes the normalized cardinal sine of a `number`

.

```
var v = sinc( 0.5 );
// returns ~0.637
v = sinc( -1.2 );
// returns ~-0.156
v = sinc( 0.0 );
// returns 1.0
v = sinc( NaN );
// returns NaN
```

```
var linspace = require( '@stdlib/array-base-linspace' );
var sinc = require( '@stdlib/math-base-special-sinc' );
var x = linspace( -5.0, 5.0, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( sinc( x[ i ] ) );
}
```
