X02ALF

X02ALF returns the largest positive floating-point number.

X02ALF returns the largest positive number in the model of floating-point arithmetic described in the X02 Chapter Introduction. The returned value is equal to $\left(1-b^{-p}\right)\times b^{e_{\max }}$, where $b$ is the arithmetic base (see X02BHF) and $e_{\max }$ is the maximum exponent (see X02BLF) in the model.
