/**
* Computes the dot product of two single-precision floating-point vectors.
*
* @param {VectorLike} x - first input array
* @param {VectorLike} y - second input array
* @throws {TypeError} first argument must be a 1-dimensional ndarray containing single-precision floating-point numbers
* @throws {TypeError} second argument must be a 1-dimensional ndarray containing single-precision floating-point numbers
* @throws {RangeError} input arrays must be the same length
* @returns {number} dot product
*
* @example
* var Float32Array = require( '@stdlib/array/float32' );
* var array = require( '@stdlib/ndarray/array' );
*
* var x = array( new Float32Array( [ 4.0, 2.0, -3.0, 5.0, -1.0 ] ) );
* var y = array( new Float32Array( [ 2.0, 6.0, -1.0, -4.0, 8.0 ] ) );
*
* var z = sdot( x, y );
* // returns -5.0
