Advanced tools
Return an unsigned 32-bit integer corresponding to the IEEE 754 binary representation of a single-precision floating-point number.
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
Return an unsigned 32-bit integer corresponding to the IEEE 754 binary representation of a single-precision floating-point number.
npm install @stdlib/number-float32-base-to-word
var toWordf = require( '@stdlib/number-float32-base-to-word' );
Returns an unsigned 32-bit integer corresponding to the IEEE 754 binary representation of a single-precision floating-point number.
var float64ToFloat32 = require( '@stdlib/number-float64-base-to-float32' );
var f32 = float64ToFloat32( 1.337 );
// returns 1.3370000123977661

#include "stdlib/number/float32/base/to_word.h"
Converts a single-precision floating-point number to an unsigned 32-bit integer corresponding to the number's IEEE 754 binary representation.
#include <stdint.h>
uint32_t word;
stdlib_base_float32_to_word( 3.14f, &word );
The function accepts the following arguments:
[in] float input value.[out] uint32_t* destination.void stdlib_base_float32_to_word( const float x, uint32_t *word );
An opaque type definition for a union for converting between a single-precision floating-point number and an unsigned 32-bit integer.
#include <stdint.h>
stdlib_base_float32_word_t w;
// Assign a single-precision floating-point number:
w.value = 3.14f;
// Retrieve the word:
uint32_t word = w.word;
The union has the following members:
float single-precision floating-point number.uint32_t word.#include "stdlib/number/float32/base/to_word.h"
#include <stdint.h>
#include <stdio.h>
int main( void ) {
float x[] = { 3.14f, -3.14f, 0.0f, 0.0f/0.0f };
uint32_t word;
int i;
for ( i = 0; i < 4; i++ ) {
stdlib_base_float32_to_word( x[ i ], &word );
printf( "%f => word: %u\n", x[ i ], word );
}
}
