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. See also: sqrt, lsqrt64

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. See also: sqrt, lsqrt
