Binary String
Return a string giving the literal bit representation of an unsigned 8-bit integer.
Usage
var toBinaryString = require( '@stdlib/number/uint8/base/to-binary-string' );
toBinaryString( x )
Returns a string giving the literal bit representation of an unsigned 8-bit integer.
var Uint8Array = require( '@stdlib/array/uint8' );
var a = new Uint8Array( [ 1, 4, 9 ] );
var str = toBinaryString( a[0] );
// returns '00000001'
str = toBinaryString( a[1] );
// returns '00000100'
str = toBinaryString( a[2] );
// returns '00001001'
Notes
Except for typed arrays, JavaScript does not provide native user support for unsigned 8-bit integers. According to the ECMAScript standard,
numbervalues correspond to double-precision floating-point numbers. While this function is intended for unsigned 8-bit integers, the function will accept floating-point values and represent the values as if they are unsigned 8-bit integers. Accordingly, care should be taken to ensure that only nonnegative integer values less than256(2^8) are provided.var str = toBinaryString( 1 ); // returns '00000001' str = toBinaryString( 4 ); // returns '00000100' str = toBinaryString( 9 ); // returns '00001001' str = toBinaryString( 255 ); // returns '11111111'
Examples
var Uint8Array = require( '@stdlib/array/uint8' );
var MAX_UINT8 = require( '@stdlib/constants/uint8/max' );
var toBinaryString = require( '@stdlib/number/uint8/base/to-binary-string' );
var x;
var y;
var b;
var i;
x = new Uint8Array( MAX_UINT8+1 );
for ( i = 0; i < x.length; i++ ) {
x[ i ] = i;
}
// Convert unsigned 8-bit integers to literal bit representations...
for ( i = 0; i < x.length; i++ ) {
b = toBinaryString( x[i] );
y = parseInt( b, 2 );
console.log( 'x: %d, b: %s, y: %d', x[i], b, y );
