# IEE754 constants

m_epsilon :: Double #

The smallest `Double` ε such that 1 + ε ≠ 1.

m_sqrt_eps :: Double #

    sqrt m_epsilon

Since: 0.3.3.0

m_huge :: Double #

Largest representable finite value.

m_tiny :: Double #

m_pos_inf :: Double #

Positive infinity.

m_neg_inf :: Double #

Negative infinity.

m_NaN :: Double #

Not a number.

m_max_log :: Double #
