INTEGER( ) Convert expression to integer

Domain: Conversion functions

The INTEGER( ) function converts any expression to the data type INTEGER. In doing this, STRING expressions are converted according to the rules of implicit conversion. The following applies to BOOLEAN expressions: TRUE is converted to the value 1, FALSE to 0.

The IS-INTEGER function can be used to first check whether a STRING expression can be converted.

Example

The variables A, B, C and D are initialized:

/A = '4'
/B = 5
/C = 30
/D = TRUE    “Type: BOOLEAN” 
/AINT = INTEGER(EXPRESSION = A)
/SHOW-VARIABLE AINT
AINT = 4
BINT = INTEGER(EXPRESSION = B + C)
/SHOW-VARIABLE BINT
BINT = 35
/CINT = INTEGER(EXPRESSION = D)
/SHOW-VARIABLE CINT
CINT = 1
