IS_NANIS_NAN(X)Description Returns TRUE if the value is a NaN value.
IEEE_DIVIDEIEEE_DIVIDE(X, Y)Description Divides X by Y; this function never fails. Returns FLOAT64. Unlike the division operator (/), this function does not generate errors for division by zero or overflow.
RANDRAND()Description Generates a pseudo-random value of type FLOAT64 in the range of [0, 1), inclusive of 0 and exclusive of 1. SQRTSQRT(X)Description Computes the square root of X. Generates an error if X is less than 0.
