Float (data type)

Floats

Floats are one of the primitive data types supported by nyan. They are used for representing fractions and rational numbers. Floats can be positive, negative or infinite (noted as inf).

Syntax

positive_float : float = 2.05
negative_float : float = -15.234
infinite_float : float = inf

Example

Unit():
    speed : float

Archer(Unit):
    speed = 2.03

The float speed has a value of 2.03.

Operators

(Re-)Assignment '='

Unit():
    speed : float = 1.0

Archer(Unit):
    speed = 0.9

Overwrites the old value with a new one.

Addition '+='

Archer(Unit):
    speed = 1.05

FasterArchers<Archer>():
    speed += 0.56

Adds a given value to the float.

Substraction '-='

Archer(Unit):
    speed = 1.05

SlowerArchers<Archer>():
    speed -= 0.56

Substracts a given value from the float.

Multiplication '*='

Archer(Unit):
    speed = 1.05

SpeedyArchers<Archer>():
    speed *= 2.5

Multiplies a float by another float or an integer.

Division '/='

Archer(Unit):
    speed = 1.05

SnailArchers<Archer>():
    speed /= 1.5

Divides a float by another float or an integer.
