nag_real_largest_number (X02ALC) returns the largest positive number in the model of floating-point arithmetic described in the x02 Chapter Introduction. The returned value is equal to

(1 - b^{- p}) \times b^{e_{\max}}

, where

b

is the arithmetic base (see nag_real_base (X02BHC)) and

e_{\max}

is the maximum exponent (see nag_real_max_exponent (X02BLC)) in the model.
