writeDouble

Writes eight bytes of a bit representation of double, in the big-endian order, to this sink. Bit representation of the double corresponds to the IEEE 754 floating-point "double format" bit layout.

To obtain a bit representation, the Double.toBits function is used.

Should be used with care when working with special values (like NaN) as bit patterns obtained for Double.NaN may vary depending on a platform.

Parameters

double

the floating point number to be written.

Throws

when the sink is closed.

Samples

import kotlinx.io.*
import kotlin.test.*

fun main() { 
   //sampleStart 
   val buffer = Buffer()
buffer.writeDouble(123456.78901)

assertContentEquals(byteArrayOf(64, -2, 36, 12, -97, -56, -13, 35), buffer.readByteArray()) 
   //sampleEnd
}
