Mathematical Functions (Transact-SQL)

[!INCLUDE sql-asdb-asdbmi-asa-pdw-fabricse-fabricdw]

The following scalar functions perform a calculation, usually based on input values that are provided as arguments, and return a numeric value:

• ABS
• ACOS
• ASIN
• ATAN
• ATN2
• CEILING
• COS
• COT
• DEGREES
• EXP
• FLOOR
• LOG
• LOG10
• PI
• POWER
• RADIANS  
• RAND  
• ROUND  
• SIGN  
• SIN  
• SQRT  
• SQUARE  
• TAN

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. This means 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.
