function significandf( x ) {
	// Convert `x` to an unsigned 32-bit integer corresponding to the IEEE 754 binary representation:
	var w = getWord( x );

	// Apply a mask to isolate only the significand bits:
	return w & MASK;
}
Returns an integer corresponding to the significand of a single-precision floating-point number.

@param {number} x - single-precision floating-point number
@returns {uinteger32} significand

@example
var toFloat32 = require( '@stdlib/number/float64/base/to-float32' );
var s = significandf( toFloat32( 3.14e34 ) ); // => 10000011000010001110111
// returns 4293751

@example
var toFloat32 = require( '@stdlib/number/float64/base/to-float32' );
var s = significandf( toFloat32( 3.14e-34 ) ); // => 10100001011000001010101
// returns 5288021

@example
var toFloat32 = require( '@stdlib/number/float64/base/to-float32' );
var s = significandf( toFloat32( -3.14 ) ); // => 10010001111010111000011
// returns 4781507

@example
var s = significandf( 0.0 ); // => 00000000000000000000000
// returns 0

@example
var s = significandf( NaN ); // => 10000000000000000000000
// returns 4194304
