This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/math-base-special-floorsd) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

About stdlib...
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!
floorsd
Round a numeric value to the nearest number toward negative infinity with N significant figures.
Installation
npm install @stdlib/math-base-special-floorsdUsage
var floorsd = require( '@stdlib/math-base-special-floorsd' );floorsd( x, n, b )
Rounds a numeric value to the nearest number toward negative infinity with n significant figures.
var v = floorsd( 3.141592653589793, 5, 10 );
// returns 3.1415
v = floorsd( 3.141592653589793, 1, 10 );
// returns 3.0
v = floorsd( 12368.0, 2, 10 );
// returns 12000.0
v = floorsd( 0.0313, 2, 2 );
// returns 0.03125Examples
var randu = require( '@stdlib/random-base-randu' );
var floorsd = require( '@stdlib/math-base-special-floorsd' );
var x;
var y;
var i;
for ( i = 0; i < 100; i++ ) {
x = (randu()*10000.0) - 5000.0;
y = floorsd( x, 5, 10 );
console.log( 'x: %d. Rounded: %d.', x, y );

Usage
#include "stdlib/math/base/special/floorsd.h"stdlib_base_floorsd( x, n, b )
Rounds a numeric value to the nearest number toward negative infinity with n significant figures.
double out = stdlib_base_floorsd( 0.0313, 2, 2 );
// returns 0.03125The function accepts the following arguments:
- x:
[in] doubleinput value. - n:
[in] int32_tnumber of significant figures. - b:
[in] int32_tbase.
double stdlib_base_floorsd( const double x, const int32_t n, const int32_t b );Examples
#include "stdlib/math/base/special/floorsd.h"
#include <stdio.h>
#include <stdint.h>
int main( void ) {
const double x[] = { -5.0, -3.89, -2.78, -1.67, -0.56, 0.56, 1.67, 2.78, 3.89, 5.0 };
const int32_t n[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
const int32_t b[] = { 20, 19, 18, 17, 16, 15, 14, 13, 12, 11 };
