# pointNorm -- compute the "projectivized" norm of the given point

## Synopsis

• Usage:
n = pointNorm(p)
• Inputs:
• p, ,

## Description

For the given point this function computes the "projectivized" norm (square root of $1+ x_1^2 + ... + x_n^2$) of the given point. This will be used in order to compute the gamma value.

 i1 : p = point {{.2,3}}; i2 : pointNorm(p) o2 = 3.16859590355097 o2 : RR (of precision 53)

## Ways to use pointNorm :
