Enum FloatError 

pub enum FloatError {
    Integer,
    InvalidSuffix,
    MissingExponent,
    NoExponentDigits,
    NoDigits,
    TooManyPoints,
    DecimalFloat,
    UnsupportedType,
}

Why a preprocessing number is not a floating constant.

FloatError::Integer is not a diagnostic, in the same way IntError::Floating is not: it means the spelling belongs to the other path.

Variants

Integer

This is an integer constant. Nothing is wrong with it.

InvalidSuffix

The characters after the number are not a suffix.

MissingExponent

A hexadecimal floating constant with no p exponent. The exponent is required there and not optional as it is in a decimal one, because f is a hexadecimal digit and there would be no way to tell a suffix from the number.

NoExponentDigits

An e or a p with no digits after it.

NoDigits

A constant with a point and no digits at all.

TooManyPoints

More than one point, which is a preprocessing number and not a constant.

DecimalFloat

A df, dd or dl suffix. The constant is well formed and this compiler has nowhere to put a decimal floating value yet.

UnsupportedType

A suffix naming a type this target does not have, which is w anywhere but x86 and f128x everywhere.
