Mathematical Functions
These scalar functions perform a calculation, usually based on input values provided as arguments, and return a numeric value.
ABS | DEGREES | RAND |
ACOS | EXP | ROUND |
ASIN | FLOOR | SIGN |
ATAN | LOG | SIN |
ATN2 | LOG10 | SQUARE |
CEILING | PI | SQRT |
COS | POWER | TAN |
COT | RADIANS |
Note Arithmetic functions, such as ABS, CEILING, DEGREES, FLOOR, POWER, RADIANS, and SIGN, return a value having the same data type as the input value. Trigonometric and other functions, including EXP, LOG, LOG10, SQUARE, and SQRT, cast their input values to float and return a float value.
All mathematical functions, except for RAND, are deterministic functions; they return the same results each time they are called with a specific set of input values. RAND is deterministic only when a seed parameter is specified. For more information about function determinism, see Deterministic and Nondeterministic Functions.
