Methods in this pseudo-class can be executed on integer values.
More...
|
string | format (string fmt) |
| Returns a string of a formatted number according to a format string.
|
|
bool | intp () |
| Returns True by default.
|
|
int | sign () |
| Returns -1 if the number is negative, 0 if it is zero, or 1 if it is positive.
|
|
bool | strp () |
| Returns True because integer values can be converted to strings.
|
|
int | typeCode () |
| Returns Qore::NT_INT.
|
|
bool | val () |
| Returns True if the int is non-zero, False if zero.
|
|
bool | callp () |
| Returns False; this method is reimplemented in other types and will return True if the given expression is a callable value (ie closures or call references)
|
|
bool | empty () |
| Returns True; this method will be reimplemented in container types where it may return False.
|
|
bool | intp () |
| Returns False; this method is reimplemented in other types and will return True if the given expression can be converted to an integer.
|
|
AbstractIterator | iterator () |
| Returns an iterator object for the value; the default iterator object returned is SingleValueIterator.
|
|
int | lsize () |
| Returns 1; the return value of this method should give the list size of the value, which is normally 1 for non-lists (except for NOTHING where the size will be 0) and the number of the elements in the list for lists; this method will be reimplemented in other types where it may return other values.
|
|
int | size () |
| Returns zero; this method will be reimplemented in container types where it may return a non-zero value.
|
|
bool | strp () |
| Returns False; this method is reimplemented in other types and will return True if the given expression can be converted to a string.
|
|
bool | toBool () |
| Returns the boolean representation of the value; the default is False.
|
|
float | toFloat () |
| Returns the floating-point representation of the value; the default is 0.0.
|
|
int | toInt () |
| Returns the integer representation of the value; the default is 0.
|
|
string | toString () |
| Returns the string representation of the value; the default is an empty string.
|
|
string | type () |
| Returns the string type for the value.
|
|
int | typeCode () |
| Returns the type code for the value.
|
|
bool | val () |
| Returns False; this method is reimplemented in other types and will return True if the given expression has a value.

Returns a string of a formatted number according to a format string.
- Code Flags:
- CONSTANT
- Parameters
-
fmt | the format string has the following format:
<thousands_separator>[ <decimal_separator><decimals>]
where:
- thousands_separator and decimal_separator are single ASCII characters defining the thousands and decimal separator characters respectively, and
- decimals is a single digit defining how may decimals should appear after the decimal point - if this is non-zero then the decimals will all be
"0"
|
- Returns
- a string of a formatted number according to a format string; if the format string does not follow the given format, then an empty string is returned
- Example:
my int $i = -48392093894;
my string $nstr = $i.format(".,3"); # returns "-48.392.093.894,000"
