asinh
Compute the hyperbolic arcsine of a double-precision floating-point number.
Usage
var asinh = require( '@stdlib/math/base/special/asinh' );
asinh( x )
Computes the hyperbolic arcsine of a double-precision floating-point number.
var v = asinh( 0.0 );
// returns 0.0
v = asinh( -0.0 );
// returns -0.0
v = asinh( 2.0 );
// returns ~1.444
v = asinh( -2.0 );
// returns ~-1.444
v = asinh( NaN );
// returns NaN
v = asinh( -Infinity );
// returns -Infinity
v = asinh( Infinity );
// returns Infinity
Examples
var linspace = require( '@stdlib/array/base/linspace' );
var asinh = require( '@stdlib/math/base/special/asinh' );
var x = linspace( -5.0, 5.0, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( asinh( x[ i ] ) );
}
C APIs
Usage
#include "stdlib/math/base/special/asinh.h"
stdlib_base_asinh( x )
Computes the hyperbolic arcsine of a double-precision floating-point number.
double out = stdlib_base_asinh( 2.0 );
// returns ~1.444
out = stdlib_base_asinh( -2.0 );
// returns ~-1.444
The function accepts the following arguments:
- x:
[in] double
input value.
double stdlib_base_asinh( const double x );
Examples

double v;
int i;
for ( i = 0; i < 10; i++ ) {
v = stdlib_base_asinh( x[ i ] );
printf( "asinh(%lf) = %lf\n", x[ i ], v );
}
