stringExp should be a string that consists of a number which has 64 bits or less than. For a value of more than 64 bits, the result of float(stringExp) is imprecise.

numberExp should be a numeric value which has 64 bits or less. For a value of more than 64 bits, the result of float(numberExp) is imprecise.
