Description
arg
ByVal
numeric, Boolean, String or Enum
The value to convert to Integer.
Discussion
This function converts any numeric or enumeration value to an Integer value. See the table below for
details of the conversion.
Input Type
Result
Byte, Boolean
High byte zero, low byte as supplied.
Integer
No effect, the value is as supplied.
UnsignedInteger
Value bits are the same as supplied, although interpreted
as a signed value.
Enum
The resulting value is the Enum member value.
Long
The resulting value will be the low word of the supplied
value.
UnsignedLong
The resulting value will be the low word of the supplied
value.
Single
The supplied value is converted to signed 32-bit integer,
rounded to the nearest integer. If the fractional part is
exactly 0.5, the resulting integer will be even. This is
known as “statistical rounding”. If the resulting integer is
larger than will fit in 16-bits, the result is undefined.
String
The result is the numeric value of the characters in the
string, ignoring leading space and tab characters. The
value string may begin with a plus or minus sign and an
optional radix indicator (&H for hexadecimal, &O for octal,
&B or &X for binary, all case insensitive). The conversion
is terminated upon reaching the end of the string or
encountering the first character that is not valid for the
indicated radix.
Example
Dim i as Integer
i = CInt(2.5)
' result is 2
i = CInt(1.5)
' result is 2
