isPositiveZerof

Test if a single-precision floating-point numeric value is positive zero.

Installation

npm install @stdlib/math-base-assert-is-positive-zerof

Usage

var isPositiveZerof = require( '@stdlib/math-base-assert-is-positive-zerof' );

isPositiveZerof( x )

Tests if a single-precision floating-point numeric value is positive zero.

var bool = isPositiveZerof( 0.0 );
// returns true

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

Examples

var isPositiveZerof = require( '@stdlib/math-base-assert-is-positive-zerof' );

var bool = isPositiveZerof( 0.0 );
// returns true

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

bool = isPositiveZerof( 5.0 );
// returns false

bool = isPositiveZerof( -1.0 );
// returns false

bool = isPositiveZerof( NaN );
// returns false
