FABS(3) BSD Library Functions Manual FABS(3)NAME
fabs -- floating-point absolute value function
SYNOPSIS
#include <math.h>
double
fabs(double x);
long double
fabsl(long double x);
float
fabsf(float x);
DESCRIPTION
The fabs() functions compute the absolute value of a floating-point number x.
SPECIAL VALUES
fabs(+-0) returns 0.
fabs(+-infinity) returns +infinity.
VECTOR OPERATIONS
If you need to apply the fabs() 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 vfabsf(vFloat x);
void vvfabsf( float *y, const float *x, const int *n);
void vvfabs(double *y, const double *x, const int *n);
SEE ALSO abs(3), ceil(3), floor(3), rint(3), math(3)STANDARDS
The fabs() functions conform to ISO/IEC 9899:2011.

FMOD(3) BSD Library Functions Manual FMOD(3)NAME
fmod -- floating-point remainder function
SYNOPSIS
#include <math.h>
double
fmod(double x, double y);
long double
fmodl(long double x, long double y);
float
fmodf(float x, float y);
DESCRIPTION
The fmod() functions compute the floating-point remainder of x/ y.
Specifically, the functions return the value x-i*y, for some integer i such that, if y is non-zero, the result has the same sign as x and
magnitude less than the magnitude of y.
SPECIAL VALUES
fmod(+-0, y) returns +-0 if y is neither 0 nor NaN.
fmod(x, y) returns a NaN and raises the "invalid" floating-point exception for x infinite or y zero.
fmod(x, +-infinity) returns x for x not infinite.
VECTOR OPERATIONS
If you need to apply the fmod() functions to SIMD vectors or arrays, using the following functions provided by the Accelerate.framework may
give significantly better performance:
#include <Accelerate/Accelerate.h>
vFloat vfmodf(vFloat x, vFloat y);
void vvfmodf(float *z, const float *y, const float *x, const int *n);
void vvfmod(double *z, const double *y, const double *x, const int *n);
SEE ALSO math(3)STANDARDS
The fmod() functions conform to ISO/IEC 9899:2011.

Hello!
I'm about to embark on a new project to port the VPM (Variable Permability Model) for decompression diving from some old BASIC code (attached, "VPM.txt") to PHP.

Tonight I was looking into maybe creating a new front end using something like this (see video below) where the database stays the same but the user interaction happens in a virtual scifi world, such as 3D Scifi Base Vol 1 which is a 3D Models/Environments in Sci-Fi for Unity.
