Dbl2Float()
- Provides safe type
casting from double to float with an indication of overflow
returned in the valid
parameter. Depending on
machine/compiler settings, the following code may throw an
under/over-flow exception or quietly return an undefined value:
// unsafe
float val = (float)_tcstod(pNptr, ppEndptr);
A safer method would be:
BOOL valid = false;
float val = Dbl2Flt(_tcstod(pNptr, ppEndptr),
&valid);
Dbl2Int()
- Provides safe type casting from double to int with an indication
of overflow returned in the valid
parameter.mod()
- This function returns the mathematical modulo operation and
handles negatives correctly. The standard math functions
fmod()
and fmodf()
and the operator %
will return negative results if the first operand is negative. This
function will always return a positive remainder.SinCos()
- Returns both the sine and cosine of the angle specified, as
floats. This function uses assembly language on Intel CPUs.Sin()
- Returns the sine of the angle specified as a float. This function
uses assembly language on Intel CPUs.Cos()
- Returns the cosine of the angle specified as a float. This
function uses assembly language on Intel CPUs.Sqrt()
- Returns the square root of the argument specified as a float.
This function uses assembly language on Intel CPUs.sramp()
- This function makes a kind of straight-segment S curve. The
parameters are x, a, b, d. The algorithm is as follows:IsDebugging()
- Returns true if 3ds Max is running under the debugger; otherwise
false.NumberOfProcessors()
- Returns the number of processors in the machine 3ds Max is
running on.
IsWindows9x()
- Returns true if 3ds Max is running on
Windows 9x (95 or 98); otherwise false.
IsWindows98or2000()
- Returns true if 3ds Max is running
on Windows 98 or Windows 2000; otherwise false.GetScreenWidth()
- Returns the width of the screen (taking into consideration if
multiple monitors are in use).GetScreenHeight()
- Returns the height of the screen (taking into consideration if
multiple monitors are in use).
