isNegativeFinite

Test if a double-precision floating-point numeric value is a negative finite number.

Usage

var isNegativeFinite = require( '@stdlib/math/base/assert/is-negative-finite' );

isNegativeFinite( x )

Tests if a double-precision floating-point numeric value is a negative finite number.

var bool = isNegativeFinite( -3.14 );
// returns true

bool = isNegativeFinite( 2.0 );
// returns false

Examples

var isNegativeFinite = require( '@stdlib/math/base/assert/is-negative-finite' );

var bool = isNegativeFinite( -3.14 );
// returns true

bool = isNegativeFinite( 3.14 );
// returns false

bool = isNegativeFinite( 0.0 );
// returns false

bool = isNegativeFinite( -0.0 );
// returns false

bool = isNegativeFinite( NaN );
// returns false
