{{alias}}( value ) Tests if a value is a nonnegative finite number. Parameters ---------- value: any Value to test. Returns ------- bool: boolean Boolean indicating whether value is a nonnegative finite number. Examples -------- > var bool = {{alias}}( 5.0 ) true > bool = {{alias}}( new {{alias:@stdlib/number/ctor}}( 5.0 ) ) true > bool = {{alias}}( 3.14 ) true > bool = {{alias}}( -5.0 ) false > bool = {{alias}}( null ) false > bool = {{alias}}( {{alias:@stdlib/constants/float64/pinf}} ) false {{alias}}.isPrimitive( value ) Tests if a value is a number primitive having a nonnegative finite value. Parameters ---------- value: any Value to test. Returns ------- bool: boolean Boolean indicating whether value is a number primitive having a nonnegative finite value. Examples -------- > var bool = {{alias}}.isPrimitive( 3.0 ) true > bool = {{alias}}.isPrimitive( new {{alias:@stdlib/number/ctor}}( 3.0 ) ) false {{alias}}.isObject( value ) Tests if a value is a number object having a nonnegative finite value. Parameters ---------- value: any Value to test. Returns ------- bool: boolean Boolean indicating whether value is a number object having a nonnegative finite value. Examples -------- > var bool = {{alias}}.isObject( 3.0 ) false > bool = {{alias}}.isObject( new {{alias:@stdlib/number/ctor}}( 3.0 ) ) true See Also --------
