isPow2Uint32
Test whether an unsigned integer is a power of 2.
Installation
npm install @stdlib/math-base-assert-uint32-is-pow2
Usage
var isPow2Uint32 = require( '@stdlib/math-base-assert-uint32-is-pow2' );
isPow2Uint32( x )
Tests whether x
is a power of 2.
var bool = isPow2Uint32( 2 );
// returns true
bool = isPow2Uint32( 5 );
// returns false
Examples
var isPow2Uint32 = require( '@stdlib/math-base-assert-uint32-is-pow2' );
var i;
for ( i = 0; i < 100; i++ ) {
console.log( 'isPow2( %d ) = %s', i, isPow2Uint32( i ) );
}
C APIs
Usage
#include "stdlib/math/base/assert/uint32_is_pow2.h"
stdlib_base_uint32_is_pow2( x )
Tests whether an unsigned integer is a power of 2.
#include <stdbool.h>
bool out = stdlib_base_uint32_is_pow2( 5 );
// returns false
out = stdlib_base_uint32_is_pow2( 2 );
// returns true
The function accepts the following arguments:
- x:
[in] uint32_t
input value.
bool stdlib_base_uint32_is_pow2( const uint32_t x );
Examples
#include "stdlib/math/base/assert/uint32_is_pow2.h"
#include <stdio.h>
#include <stdbool.h>
#include <stdint.h>
int main( void ) {
const uint32_t x[] = { 0, 1, 2, 3, 4, 5, 8, 10, 16, 1024 };
bool b;
int i;
for ( i = 0; i < 9; i++ ) {
b = stdlib_base_uint32_is_pow2( x[ i ] );
printf( "Value: %u. is a power of 2? %s.\n", x[ i ], ( b ) ? "True" : "False" );
}
}
