max
Return the maximum value.
Installation
npm install @stdlib/math-base-special-max
Usage
var max = require( '@stdlib/math-base-special-max' );
max( [x[, y[, ...args]]] )
Returns the maximum value.
var v = max( 4.2, 3.14 );
// returns 4.2
v = max( +0.0, -0.0 );
// returns +0.0
v = max( 4.2, 3.14, -1.0, 6.8 );
// returns 6.8
If any argument is NaN
, the function returns NaN
.
var v = max( 4.2, NaN );
// returns NaN
v = max( NaN, 3.14 );
// returns NaN
If not provided any arguments, the function returns -infinity
.
var v = max();
// returns -Infinity
Notes
- When an empty set is considered a subset of the extended reals (all real numbers, including positive and negative infinity), negative infinity is the least upper bound. Similar to zero being the identity element for the sum of an empty set and to one being the identity element for the product of an empty set, negative infinity is the identity element for the maximum, and thus,
max() = -infinity
.
Examples
var minstd = require( '@stdlib/random-base-minstd-shuffle' );
var max = require( '@stdlib/math-base-special-max' );
var x;
var y;
var v;
var i;
for ( i = 0; i < 100; i++ ) {
x = minstd();
y = minstd();
v = max( x, y );
console.log( 'max(%d,%d) = %d', x, y, v );
}
