Less than or equal to comparison.

Args:

  • ​rhs (Self): The value to compare.

Returns:

True if this value is less than or equal to rhs.

__eq__​

__eq__(self: Self, rhs: Self) -> Bool

Compare for equality.

Args:

  • ​rhs (Self): The value to compare.

Returns:

True if they are equal.

__gt__​

__gt__(self: Self, rhs: Self) -> Bool

Greater than comparison.

Args:

  • ​rhs (Self): The value to compare.

Returns:

True if this value is greater than rhs.

__ge__​

__ge__(self: Self, rhs: Self) -> Bool

Greater than or equal to comparison.

Args:

  • ​rhs (Self): The value to compare.

Returns:

True if this value is greater than or equal to rhs.

__add__​

__add__(self: Self, rhs: Self) -> Self

Add two FloatLiterals.

Args:

  • ​rhs (Self): The value to add.

Returns:

The sum of the two values.

__sub__​

__sub__(self: Self, rhs: Self) -> Self

Subtract two FloatLiterals.

Args:

  • ​rhs (Self): The value to subtract.

Returns:

The difference of the two values.

__mul__​

__mul__(self: Self, rhs: Self) -> Self

Multiply two FloatLiterals.

Args:

  • ​rhs (Self): The value to multiply.

Returns:

The product of the two values.

__truediv__​

__truediv__(self: Self, rhs: Self) -> Self

__floordiv__​

__floordiv__(self: Self, rhs: Self) -> Self

Returns self divided by rhs, rounded down to the nearest integer.

Args:

  • ​rhs (Self): The divisor value.

Returns:

floor(self / rhs) value.

__mod__​

__mod__(self: Self, rhs: Self) -> Self

Return the remainder of self divided by rhs.

Args:

  • ​rhs (Self): The value to divide on.

Returns:

The remainder of dividing self by rhs.

__radd__​

__radd__(self: Self, rhs: Self) -> Self

Reversed addition operator.

Args:

  • ​rhs (Self): The value to add.

Returns:

The sum of this and the given value.

__rsub__​

__rsub__(self: Self, rhs: Self) -> Self

Reversed subtraction operator.

Args:

  • ​rhs (Self): The value to subtract from.

Returns:

The result of subtracting this from the given value.

__rmul__​

__rmul__(self: Self, rhs: Self) -> Self

Reversed multiplication operator.

Args:

  • ​rhs (Self): The value to multiply.

Returns:

The product of the given number and this.

__rtruediv__​

__rtruediv__(self: Self, rhs: Self) -> Self

Reversed division.

Args:

  • ​rhs (Self): The value to be divided by this.

Returns:

The result of dividing the given value by this.

__rfloordiv__​

__rfloordiv__(self: Self, rhs: Self) -> Self

Returns rhs divided by self, rounded down to the nearest integer.

Args:

  • ​rhs (Self): The value to be divided by self.

Returns:

floor(rhs / self) value.

__iadd__​

__iadd__(inout self: Self, rhs: Self)

In-place division.

Args:

  • ​rhs (Self): The value to divide.

is_nan​

is_nan(self: Self) -> Bool

Return whether the FloatLiteral is nan.

Since nan == nan is False, this provides a way to check for nan-ness.

Returns:

True, if the value is nan, False otherwise.

is_neg_zero​

is_neg_zero(self: Self) -> Bool

Return whether the FloatLiteral is negative zero.

Since FloatLiteral.negative_zero == 0.0 is True, this provides a way to check if the FloatLiteral is negative zero.

Returns:

True, if the value is negative zero, False otherwise.
