Modifier and Type	Method and Description
static boolean	isIntegerNumber(java.lang.String word) Returns true if the word is an integer number; else returns false If it's a natural number, it's an integer number
static boolean	isNaturalNumber(java.lang.String word) Returns true if the word is a natural number; else returns false
static boolean	isNumber(java.lang.String word) Returns true if the word is a number; else returns false
static boolean	isRealNumber(java.lang.String word) Returns true if the word is a real number; else returns false It's supposed that '.' is the symbol for separate integer from decimal part If it's a natural or integer, it's a real number
static boolean	isRealNumberWithIntegerExponent(java.lang.String word) Returns true if the word is a real number with or without the 'E' (or 'e') symbol for the exponent; else returns false It's supposed that '.' is the symbol for separate integer from decimal part in the base.
static boolean	isRealNumberWithRealExponent(java.lang.String word) Returns true if the word is a real number with or without the 'E' (or 'e') symbol for the exponent; else returns false It's supposed that '.' is the symbol for separate integer from decimal part, in the base and the exponent of the number If it's a natural, integer, real number or real number with integer exponent, it's a real number with real exponent
