Fract/Exp String To NumberInterprets the characters 0 through 9, plus, minus, e, E, and the decimal point (usually period) in string starting at offset as a floating-point number in engineering notation, exponential, or fractional format and returns it in number.
Hexadecimal String To NumberInterprets the characters 0 through 9, A through F, and a through f in string starting at offset as a hex integer and returns it in number.
Number To Decimal StringConverts number to a string of decimal digits at least width characters wide or wider if necessary. If number is floating-point or fixed-point, it is rounded to a 64-bit integer before conversion.
