number uIsAscending(params, ...)
A list of expressions or values of any data type.
Check multiple values for an ascending order
uIsAscending("A", "B", "C") // returns 1
uIsAscending("A", "A", "C") // returns 1
uIsAscending("A", "C", "B") // returns 0
uIsAscending("1", "2", "3") // returns 1
uIsAscending("3", "2", "2") // returns 0
uIsAscending("2004-03-03", "2004-03-05", "2004-03-07")
// returns 1
uIsAscending("2004-03-03", "2004-03-07", "2004-03-05")
//returns 0
Returns 1 if the parameter is:
one of 1, true, or yes
0, no, or false
Returns 1 if the parameter is
number uIsBoolean(param)
An expressions or value of any data type.
Check for boolean value:
uIsBoolean("1") // returns 1
uIsBoolean("yes") // returns 1
uIsBoolean("true") // returns 1
uIsBoolean("-1") // returns 0
uIsBoolean("0") // returns 1
Returns 1 if the parameter can be interpreted as a date. If the second parameter is omitted, the function tries to apply one the following formats:
y-M-D H:N:S.s
y-M-D H:N:S
y-M-D
H:N:S
For details about the format string, refer to the uConvertDate function.
number uIsDate(datestring [, format])
The string to be checked.
The format of the input date
uIsDate("2004-02-29") // returns 1
uIsDate("2003-02-29") // returns 0, since 2003 was not a leap year
Returns 1 if every parameter is equal or lower than its predecessor
number uIsDescending(params, ...)
A list of expressions or values of any data type
Check multiple values for an descending order
uIsDescending("C", "B", "A") // returns 1
uIsDescending("C", "C", "A") // returns 1
uIsDescending("A", "C", "B") // returns 0
uIsDescending("3", "2", "1") // returns 1
uIsDescending("3", "2", "3") // returns 0
uIsDescending("2004-03-20", "2004-03-15", "2004-03-
07") // returns 1
uIsDescending("2004-03-20", "2004-03-07", "2004-03-
15") // returns 0
Returns 1 if the parameter is empty or null
number uIsEmpty(param)
An expression or value to investigate
uIsEmpty("1") // returns 0
uIsEmpty(null) // returns 1
uIsEmpty("") // returns 1
Returns 1 if the parameter can be interpreted as an integer value
number uIsInteger(param)
An expression or value to investigate
uIsInteger ("1") // returns 1
uIsInteger ("2.34") // returns 0
uIsInteger ("ABC") // returns 0
Returns 1 if the parameter can be interpreted as a floating point value
number uIsFloat(param)
An expression or value to investigate
uIsFloat("1") // returns 1
uIsFloat("2.34") // returns 1
uIsFloat("ABC") // returns 0
Returns 1 if the parameter is null
number uIsNull(param)
An expression or value to investigate
uIsNull("1") // returns 0
uIsNull(null) // returns 1
Returns 1 if the parameter can be interpreted as a number
number uIsNumber(param)
An expression or value to investigate
Check for a numeric value
uIsNumber("1") // returns 1
uIsNumber("2.34") // returns 1
uIsNumber("ABC") // returns 0
Returns 0 for an input of 1 and 1 for an input of 0. This function is only used in conjunction with the uIs-Functions, because the Boolean values returned are not true and false, but are 0 and 1.
number uNot(expression)
A numeric value which should be negated
uNot(1) // returns 0
