Function Documentation

unsigned long lsqrt ( unsigned long x )

Compute the square root of a number.

This function computes the square root of x using integer operations exclusively. It returns the integer that corresponds to sqrt(x).

This function operates on unsigned numbers and as such it always succeeds.

Returns:

the square root of x.

unsigned long long lsqrt64 ( unsigned long long x )

Compute the square root of a number.

This function computes the square root of x using integer operations exclusively. It returns the integer that corresponds to sqrt(x). lsqrt64 deals with 64-bit integers while lsqrt only handles 32-bit integers.

This function operates on unsigned numbers and as such it always succeeds.

Returns:

the square root of x.
