Methods in this pseudo-class can be executed on floating-point values.
More...
|
float | abs () |
| Returns the absolute value of the number. More...
|
|
string | format (string fmt) |
| Returns a string of a formatted number according to a format string. More...
|
|
bool | intp () |
| Returns True because float values can be converted to integers. More...
|
|
int | sign () |
| Returns -1 if the number is negative, 0 if it is zero, or 1 if it is positive. More...
|
|
bool | strp () |
| Returns True because float values can be converted to strings. More...
|
|
int | typeCode () |
| Returns Qore::NT_FLOAT. More...
|
|
bool | val () |
| Returns True if the float is non-zero, False if zero. More...
|
|
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) More...
|
|
bool | empty () |
| Returns True; this method will be reimplemented in container types where it may return False. More...
|
|
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. More...
|
|
AbstractIterator | iterator () |
| Returns an iterator object for the value; the default iterator object returned is SingleValueIterator. More...
|
|
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. More...
|
|
int | size () |
| Returns zero; this method will be reimplemented in container types where it may return a non-zero value. More...
|
|
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. More...
|
|
bool | toBool () |
| Returns the boolean representation of the value; the default is False. More...
|
|
float | toFloat () |
| Returns the floating-point representation of the value; the default is 0.0. More...
|
|
int | toInt () |
| Returns the integer representation of the value; the default is 0. More...
|
|
number | toNumber () |
| Returns the arbitrary-precision numeric representation of the value; the default is 0. More...
|
|
string | toString () |
| Returns the string representation of the value; the default is an empty string. More...
|
|
string | type () |
| Returns the string type for the value. More...
|
|
int | typeCode () |
| Returns the type code for the value. More...
|
|
bool | val () |
| Returns False; this method is reimplemented in other types and will return True if the given expression has a value. More...

Methods in this pseudo-class can be executed on floating-point values.
Returns the absolute value of the number.
- Code Flags:
- CONSTANT
- Example:
- Returns
- the absolute value of the number
- Note
- equivalent to abs(float)
- Since
- Qore 0.8.8
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
|
- 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 float $f = -48392093894.2349;
my string $nstr = $f.format(".,3"); # returns "-48.392.093.894,235"
- Note
- equivalent to format_number(string, softfloat)
- Since
- Qore 0.8.6
Returns True because float values can be converted to integers.
- Returns
- True because float values can be converted to integers
- Code Flags:
- CONSTANT
- Example:
if ($n.intp())
printf(
"%y: can be converted to an integer: %d\n", $n,
int($n));
Returns -1 if the number is negative, 0 if it is zero, or 1 if it is positive.
- Returns
- -1 if the number is negative, 0 if it is zero, or 1 if it is positive
- Code Flags:
- CONSTANT
- Example:
printf(
"sign: %d\n", $f.sign());
- Since
- Qore 0.8.6
Returns True because float values can be converted to strings.
- Returns
- True because float values can be converted to strings
- Code Flags:
- CONSTANT
- Example:
if ($n.strp())
printf(
"%y: can be converted to a string: '%s'\n", $n,
string($n));
