isNumberFormattedLikeAnInteger

For the slice you get from a Token.number or Token.allocated_number, this function returns true if the number doesn't contain any fraction or exponent components, and is not -0. Note, the numeric value encoded by the value may still be an integer, such as 1.0. This function is meant to give a hint about whether integer parsing or float parsing should be used on the value. This function will not give meaningful results on non-numeric input.
