x02al returns the largest positive floating-point number.

# Description

x02al returns the largest positive number in the model of floating-point arithmetic described in the

**X02**class. The returned value is equal to $\left(1-{b}^{-p}\right)\times {b}^{{e}_{\mathrm{max}}}$, where $b$ is the arithmetic base (see x02bh) and ${e}_{\mathrm{max}}$ is the maximum exponent (see (X02BLF not in this release)) in the model.# References
