# toULong

`fun Byte.toULong(): ULong`

Converts this Byte value to ULong.

If this value is positive, the resulting `ULong`

value represents the same numerical value as this `Byte`

.

The least significant 8 bits of the resulting `ULong`

value are the same as the bits of this `Byte`

value,
whereas the most significant 56 bits are filled with the sign bit of this value.

`fun Short.toULong(): ULong`

Converts this Short value to ULong.

If this value is positive, the resulting `ULong`

value represents the same numerical value as this `Short`

.

The least significant 16 bits of the resulting `ULong`

value are the same as the bits of this `Short`

value,
whereas the most significant 48 bits are filled with the sign bit of this value.

`fun Int.toULong(): ULong`

Converts this Int value to ULong.

If this value is positive, the resulting `ULong`

value represents the same numerical value as this `Int`

.

The least significant 32 bits of the resulting `ULong`

value are the same as the bits of this `Int`

value,
whereas the most significant 32 bits are filled with the sign bit of this value.

`fun Long.toULong(): ULong`

`fun Float.toULong(): ULong`

Converts this Float value to ULong.

The fractional part, if any, is rounded down.
Returns zero if this `Float`

value is negative or `NaN`

, ULong.MAX_VALUE if it's bigger than `ULong.MAX_VALUE`

.

`fun Double.toULong(): ULong`

Converts this Double value to ULong.

The fractional part, if any, is rounded down.
Returns zero if this `Double`

value is negative or `NaN`

, ULong.MAX_VALUE if it's bigger than `ULong.MAX_VALUE`

.
