SQL Server Numeric Funcs Supported by Connectivity KitLast reviewed: June 27, 1995Article ID: Q103578 |
The information in this article applies to:
SUMMARYThe Microsoft FoxPro Connectivity Kit can be used with FoxPro versions 2.5 and 2.5a for MS-DOS and Windows. The FoxPro Connectivity Kit, and the Open Database Connectivity (ODBC) specification in general, supports the minimum ANSI SQL standard. Below is a list of the SQL numeric functions that are supported.
MORE INFORMATIONThe following table lists the supported numeric-manipulation functions. Parameter arguments listed as NUMERIC_EXP or INTEGER_EXP can be numeric-type column names, numbers, or numeric results from another function call. Parameter arguments listed as FLOAT_EXP can be numeric-type column names, numbers, or numeric results from another function call that contain decimal values.
Function Description --------------------------------------------------------------- ABS(numeric_exp) Returns the absolute value of NUMERIC_EXP. ACOS(float_exp) Returns the arccosine of FLOAT_EXP as an angle expressed in radians. ASIN(float_exp) Returns the arcsine of FLOAT_EXP as an angle expressed in radians. ATAN(float_exp) Returns the arctangent of FLOAT_EXP as an angle expressed in radians. ATAN2(float_exp1, Returns the arctangent of the x and y float_exp2) represented by FLOAT_EXP1 and FLOAT_EXP2 as an angle expressed in radians. CEILING(numeric_exp) Returns the smallest integer greater than or equal to NUMERIC_EXP. COS(float_exp) Returns the cosine of FLOAT_EXP, where FLOAT_EXP is an angle expressed in radians. COT(float_exp) Returns the cotangent of FLOAT_EXP, where FLOAT_EXP is an angle expressed in radians. EXP(float_exp) Returns the exponential value of FLOAT_EXP. FLOOR(numeric_exp) Returns the largest integer less than or equal to NUMERIC_EXP. LOG(float_exp) Returns the natural logarithm of FLOAT_EXP. MOD(integer_exp1, Returns the remainder of INTEGER_EXP1 integer_exp2) divided by INTEGER_EXP2. PI() Returns the value of PI as a floating- point number. RAND([integer_exp]) Returns a random floating-point number using the optional value of integer_exp as a seed value. SIGN(numeric_exp) Returns a 0, 1, or -1 depending on whether NUMERIC_EXP is 0, positive, or negative, respectively. SIN(float_exp) Returns the sine of FLOAT_EXP, where FLOAT_EXP is an angle expressed in radians. SQRT(float_exp) Returns the square root of FLOAT_EXP. TAN(float_exp) Returns the tangent of FLOAT_EXP, where FLOAT_EXP is an angle expressed in radians.Following is an example of how the SQRT() function could be used from within FoxPro to return the square root of the number 4 into the cursor named output. This example assumes that a valid connection to an ODBC data source has already been established and that the connection handle is contained in the variable mhand.
