# Float data type

Floats are approximations of real numbers written with decimals. If you don't need to work with decimals, use the Integer data type.

```crmscript theme={null}
Integer i = 42;
Float f = 3.14;
```

<Note>
  You can create arrays of any data type to store more than one value at the same time like this: `String[] s1;`. For a given array, all items must be of the same type. Read more about [looping and accessing array items][1] in the fundamentals section.

## Constructors

### Float Float(Float value)

Pass a `Float` to copy into a new object.

```crmscript! theme={null}
Float m = 3.14;
Float pi = Float(m);
Float e = Float(2.71);
printLine(pi.toString(2) + ", " + e.toString(2));
```

### Float Float(Integer value)

Pass an `Integer` and have it converted to a `Float` object.

```crmscript! theme={null}
Integer n = 10;
Float discount = Float(n);
Float vat = Float(25);
printLine(discount.toString(1) + ", " + vat.toString(2));
```

### Float Float(Long value)

Pass a `Long` and have it converted to a `Float` object.

```crmscript! theme={null}
Long n = 314L;
Float discount = Float(n);
Float vat = Float(25);
printLine(discount.toString(1) + ", " + vat.toString(2));
```

### Float Float(String number)

Pass a `String` containing a decimal number. The constructor will parse the text and create a `Float` object.

```crmscript! theme={null}
String o = "1.618";
Float phi = Float(o);
Float twoSquared = Float("1.4142");
printLine(phi.toString(1) + ", " + twoSquared.toString(2));
```

## Numeric strings

Strings can have numeric content but are always written in quotes.

### String toString(Integer decimals)

`toString()` is one of the most frequently used methods, typically when you are going to output something. It returns a string representation of a Float.

<Note>
  You must always specify how many decimal digits you want.
</Note>

```crmscript! theme={null}
Float pi = 3.14159;
for(Integer i = 0; i < 6; i++) {
  printLine(pi.toString(i));
}
```

## Math operators

| Operator | Description |
| :------: | ----------- |
|     +    | add         |
|     -    | subtract    |
|    \*    | multiply    |
|     /    | divide      |
|     %    | reminder    |
|    ++    | increment   |
|    --    | decrement   |

## Math functions

### Float abs()

`abs()`  will return the absolute value of a Float. That is, the non-negative value of the number without regarding the sign.

```crmscript! theme={null}
Float i = -7.14;
print(i.abs().toString(2));
```

This example will print 7.14, without the sign.

### Integer floor()

`floor()` will return the Integer preceding the decimal separator. The floor of a Float is calculated by **rounding downward** to the nearest Integer.

```crmscript! theme={null}
Float f = 13.456;
print(f.floor().toString());
```

This example will print 13.

### Integer round()

`round()` will return the Integer approximation of the Float without any decimals. It is calculated by **rounding to the nearest** Integer.

* if the 1st decimal is 5, 6, 7, 8, or 9 - round up
* if the 1st decimal is 0, 1, 2, 3, 4 - round down

```crmscript! theme={null}
Float f = 13.79;
print(f.round().toString());
```

This example will print 14.

## Zero vs. no value

Before a Float is initialized, it has no value. This is commonly written as NULL, NUL, or NIL.

### Bool isNull()

`isNull()` will return **true** if it has no value and **false** if it does.
