{{alias}}( value ) Tests if a value is a finite negative number. Parameters ---------- value: any Value to test. Returns ------- bool: boolean Boolean indicating whether a value is a finite negative number. Examples -------- > var bool = {{alias}}( -5.0 ) true > bool = {{alias}}( new Number( -5.0 ) ) true > bool = {{alias}}( -3.14 ) true > bool = {{alias}}( 5.0 ) false > bool = {{alias}}( null ) false > bool = {{alias}}( -1.0/0.0 ) false > bool = {{alias}}( new Number( -1.0/0.0 ) ) false {{alias}}.isPrimitive( value ) Tests if a value is a number primitive having a finite negative value. Parameters ---------- value: any Value to test. Returns ------- bool: boolean Boolean indicating whether a value is a number primitive having a finite negative value. Examples -------- > var bool = {{alias}}.isPrimitive( -3.0 ) true > bool = {{alias}}.isPrimitive( new Number( -3.0 ) ) false > var bool = {{alias}}.isPrimitive( -1.0/0.0 ) false > bool = {{alias}}.isPrimitive( new Number( -1.0/0.0 ) ) false {{alias}}.isObject( value ) Tests if a value is a number object having a finite negative value. Parameters ---------- value: any Value to test. Returns ------- bool: boolean Boolean indicating whether a value is a number object having a finite negative value. Examples -------- > var bool = {{alias}}.isObject( -3.0 ) false > bool = {{alias}}.isObject( new Number( -3.0 ) ) true > bool = {{alias}}.isObject( -1.0/0.0 ) false > bool = {{alias}}.isObject( new Number( -1.0/0.0 ) ) false See Also --------
