Class Float
A class for representing floating point numbers as objects. Floats are approximations of real numbers written with decimals. If you don't need to work with decimals, use the Integer data type.
Examples
Integer i = 42;
Float f = 3.14;Constructors
Float(Float)
Pass a value to copy into a new object.
Declaration
Float Float(Float value)Examples
Float m = 3.14;
Float pi = Float(m);
Float e = Float(2.71);Parameters
| Type | Name | Description |
| Float | value | Float object. |
| Type | Description |
| Float |
Float(Integer)
Pass an Integer and have it converted to a Float object.
Declaration
Float Float(Integer value)Examples
Integer n = 10;
Float discount = Float(n);
Float vat = Float(25);
printLine(discount.toString(1) + ", " + vat.toString(2));Parameters
| Type | Name | Description |
| Integer | value | Integer object. |
| Type | Description |
| Float |
Float(String)
Pass a String containing a number. The constructor will parse the text and create a Float object.
Declaration
Float Float(String value)Examples
String o = "1.618";
Float phi = Float(o);
Float twoSquared = Float("1.4142");Parameters
| Type | Name | Description |
| String | value | A String containing a number. For example "3.14". |

Methods
toString(Integer)
Converts a float value to its string representation.
One of the most frequently used methods, typically when you are going to output something.Declaration
String toString(Integer decimals)Examples
Float pi = 3.14159;
for(Integer i = 0; i < 6; i++) {
printLine(pi.toString(i));
}Parameters
| Type | Name | Description |
| Integer | decimals | Number of decimal digits. |
Returns
| Type | Description |
| String |
abs()
Converts a float value to its absolute value (the non-negative value of the number without regarding the sign).
Declaration
Float abs()Examples
Float i = -7.14;
print(i.abs().toString(2));Returns
| Type | Description |
| Float |
floor()
Returns the Integer preceding the decimal separator. The floor of a Float is calculated by rounding downward to the nearest Integer.
Declaration
Integer floor()Examples
Float f = 13.456;
print(f.floor().toString())Returns
| Type | Description |
| Integer |
round()
Returns the Integer approximation of the Float without any decimals. It is calculated by rounding to the nearest Integer.
Declaration
Integer round()Examples
Float f = 13.79;
print(f.round().toString());Returns
| Type | Description |
| Integer |
isNull()
Returns true if it has no value and false if it does.
Declaration
Bool isNull()Returns
| Type | Description |
| Bool |
