Test if a finite double-precision floating-point number is a positive integer.
Test if a finite double-precision floating-point number is a positive integer.

Tests if a finite double-precision floating-point number is a positive integer
.
var bool = isPositiveInteger( 1.0 );
// returns true
bool = isPositiveInteger( 0.0 );
// returns false
bool = isPositiveInteger( -10.0 );
// returns false
The function assumes a finite number
. If provided positive infinity
, the function will return true
, when, in fact, the result is undefined. If x
can be infinite
, wrap the implementation as follows:
function check( x ) {
return (
x < Infinity &&
isPositiveInteger( x )
);
}
var bool = check( Infinity );
// returns false
var isPositiveInteger = require( '@stdlib/math-base-assert-is-positive-integer' );
var bool = isPositiveInteger( 5.0 );
// returns true
bool = isPositiveInteger( 0.0 );
// returns false
bool = isPositiveInteger( -1.0 );
// returns false
bool = isPositiveInteger( 3.14 );
// returns false
bool = isPositiveInteger( NaN );
// returns false
