SQRT(3) 						   BSD Library Functions Manual 						   SQRT(3)

NAME
sqrt -- square root function SYNOPSIS
#include <math.h> double sqrt(double x); long double sqrtl(long double x); float sqrtf(float x); DESCRIPTION
The sqrt() function compute the non-negative square root of x. SPECIAL VALUES
sqrt(-0) returns -0. sqrt(x) returns a NaN and generates a domain error for x < 0. VECTOR OPERATIONS
If you need to apply the sqrt() function to SIMD vectors or arrays, using the following functions provided by the Accelerate.framework may give significantly better performance: #include <Accelerate/Accelerate.h> vFloat vsqrtf(vFloat x); vFloat vrsqrtf(vFloat x); void vvsqrtf(float *y, const float *x, const int *n); void vvsqrt(double *y, const double *x, const int *n); void vvrsqrtf(float *y, const float *x, const int *n); void vvrsqrt(double *y, const double *x, const int *n); SEE ALSO
math(3) STANDARDS
The sqrt() function conforms to ISO/IEC 9899:2011. BSD

SIN(3)							   BSD Library Functions Manual 						    SIN(3)

NAME
sin -- sine function SYNOPSIS
#include <math.h> double sin(double x); long double sinl(long double x); float sinf(float x); DESCRIPTION
The sin() function computes the sine of x (measured in radians). SPECIAL VALUES
sin(+-0) returns +-0. sin(+-infinity) returns a NaN and raises the "invalid" floating-point exception. VECTOR OPERATIONS
If you need to apply the sin() function to SIMD vectors or arrays, using the following functions provided by the Accelerate.framework may give significantly better performance: #include <Accelerate/Accelerate.h> vFloat vsinf(vFloat x); vFloat vsincosf(vFloat x, vFloat *c); void vvsinf(float *y, const float *x, const int *n); void vvsin(double *y, const double *x, const int *n); void vvsincosf(float *s, float *c, const float *x, const int *n); void vvsincos(double *s, double *c, const double *x, const int *n); SEE ALSO
acos(3), asin(3), atan(3), atan2(3), cos(3), cosh(3), sinh(3), tan(3), tanh(3), math(3) STANDARDS

Q: Is SQRT(n) possible in a POSIX compliant shell? A: Yes within limits.

Hi all... This is just a fun project to see if it is possible to get a square root of a positive integer from 1 to 9200000 to 6 decimal places on a 64 bit architecture machine. It is coded around dash and the results show the values from 0 to 10000. Complex numbers can easily be catered for by... (3 Replies)
