Expressions and Type Conversion
Purpose
Function to determine whether a specified expression is between two other specified expressions
Syntax
INRANGE(<exp1>,<exp2>,<exp3>)
See Also
BETWEEN(), CHROVERLAP(), EMPTY(), EVALUATE(), EXPRCHECK(), INLIST(), ISALPHA(), ISBLANK(), ISDIGIT(), MAX(), MAXVALUES(), MIN(), MINVALUES(), TYPE(), VARTYPE()
Description
The INRANGE() function returns true (.T.) if the value of a specified expression lies in the range delimited by two other expressions all of the same data type. The INRANGE() function operates on Character, Date and Numeric expressions.
| Parameters | Description |
|---|---|
| <exp1> | The expression to be checked. |
| <exp2> | Expression representing the range minimum. |
| <exp3> | Expression representing the range maximum. |
The <exp1> must be equal to or more than <exp2> and equal to or less than <exp3> for INRANGE() to return true (.T). If <exp1> is not within this range, INRANGE() returns false (.F.).
Example
? inrange(date(),date()-10,date()+10) .T. ? inrange("A", "A", "Z") .T. ? inrange(10,1,9) .F.
