#include <stdinc.h>double sqr(double x)double qbe(double x)double log2(double x)double dec(double x)double powi(double x, int p)double powd(double x, double p)

**sqr(***x***)** returns the square of **x**, **qbe(***x***)** returns
the cube root of **x**, **dec***(x)* returns 10 to the power of **x**, and **log2***(x)* returns
the log to the base two of **x**. **powi***(x,p)* return the x^p, where p is any integer,
including negative, and the sign of x is taken into account properly **powd***(x,p)*
return the x^p, where for x<0 a value of 0 is returned (some machines return
NaN, others may fail).
