Elliptic integrals | |
Elliptic integrals arise occasionally in contexts relevant to us, particularly in geometric calculations involving ellipses or ellipsoids. | |
Smoothed step functions | |
Functions stepUp(), stepDown() and stepAny() provide smooth, S-shaped step functions that are useful for "softening" abrupt transitions between two values. | |
clamp(), clampInPlace() | |
Limit a numerical value so that it does not go outside a given range. | |
cube() | |
y=cube(x) returns the cube of the argument for any numeric type, integral or floating point. | |
isFinite() | |
isFinite(x) provides a reliable way to determine if x is a "normal" floating point number, meaning not a NaN or +/- Infinity. | |
isInf() | |
isInf(x) provides a reliable way to determine if x is one of the two infinities (either negative or positive). | |
isNaN() | |
isNaN(x) provides a reliable way to determine if x is one of the "not a
number" floating point forms. | |
isNumericallyEqual() | |
isNumericallyEqual(x,y) compares two scalar types using a tolerance (default or explicitly specified) and returns true if they are close enough. | |
sign() | |
s=sign(n) returns int -1,0,1 according to n<0, n==0, n>0 for any integer or real numeric type, unsigned 0 or 1 for any unsigned argument. | |
square() | |
y=square(x) returns the square of the argument for any numeric type. | |
