Adds a sign bit to allow for signed numbers.

Store values in normalized form by default. The actual precision of the significand is extended by 1 bit by assuming an implicit leading bit of 1 instead of 0. i.e. 1.nnnn instead of 0.nnnn. True for all IEE754 types

Stores the significand in IEEE754 denormalized form when the exponent is 0. Required to express the value 0.

Allows the storage of IEEE754 _infinity values.

Allows the storage of IEEE754 Not a Number values.

If set, select an exponent bias such that max_exp = 1. i.e. so that the maximum value is >= 1.0 and < 2.0. Ignored if the exponent bias is manually specified.

If set, unsigned custom floats are assumed to be negative.

If set, 0 is the only allowed IEEE754 denormalized number. Requires allowDenorm and storeNormalized.

Include _all of the IEEE754 options.

Include none of the above options.
