Compute the least common multiple (lcm) of two single-precision floating-point numbers.
npm install @stdlib/math-base-special-lcmfWe 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!

> Compute the [least common multiple][lcm] (lcm) of two single-precision floating-point numbers.
The [least common multiple][lcm] (lcm) of two non-zero integers a and b is the smallest positive integer that is divisible by both a and b. The lcm is also known as the lowest common multiple or smallest common multiple and finds common use in calculating the lowest common denominator (lcd).
``bash`
npm install @stdlib/math-base-special-lcmf
`javascript`
var lcmf = require( '@stdlib/math-base-special-lcmf' );
#### lcmf( a, b )
Computes the [least common multiple][lcm] (lcm) of two single-precision floating-point numbers.
`javascript`
var v = lcmf( 48, 18 );
// returns 144
If either a or b is 0, the function returns 0.
`javascript
var v = lcmf( 0, 0 );
// returns 0
v = lcmf( 2, 0 );
// returns 0
v = lcmf( 0, 3 );
// returns 0
`
Both a and b must have integer values; otherwise, the function returns NaN.
`javascript
var v = lcmf( 3.14, 18 );
// returns NaN
v = lcmf( 48, 3.14 );
// returns NaN
v = lcmf( NaN, 18 );
// returns NaN
v = lcmf( 48, NaN );
// returns NaN
`
`javascript
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var lcmf = require( '@stdlib/math-base-special-lcmf' );
var opts = {
'dtype': 'float32'
};
var a = discreteUniform( 100, 0, 50, opts );
var b = discreteUniform( 100, 0, 50, opts );
logEachMap( 'lcmf(%0.4f,%0.4f) = %0.4f', a, b, lcmf );
`

`c`
#include "stdlib/math/base/special/lcmf.h"
#### stdlib_base_lcmf( a, b )
Computes the [least common multiple][lcm] (lcm) of two single-precision floating-point numbers.
`c`
float v = stdlib_base_lcmf( 48.0f, 18.0f );
// returns 144.0f
The function accepts the following arguments:
- a: [in] float input value.[in] float
- b: input value.
`c`
float stdlib_base_lcmf( const float a, const float b );
`c
#include "stdlib/math/base/special/lcmf.h"
#include
int main( void ) {
const float a[] = { 24.0f, 32.0f, 48.0f, 116.0f, 33.0f };
const float b[] = { 12.0f, 6.0f, 15.0f, 52.0f, 22.0f };
float out;
int i;
for ( i = 0; i < 5; i++ ) {
out = stdlib_base_lcmf( a[ i ], b[ i ] );
printf( "lcmf(%f, %f) = %f\n", a[ i ], b[ i ], out );
}
}
