Scala Double ==(x: Char) 方法
在 Scala 中,Double 是一个 64 位浮点数,相当于 Java 的 double 基本类型。如果该值等于 x,则使用==(x: Char)方法返回 true,否则返回 false。
Method Definition – def ==(x: Char): Boolean
Returns – Returns true if this value is equal to x, false otherwise.
示例 #1:
// Scala program to explain the working
// of Double ==(x: Char) method
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Applying ==(x: Char) function
val result = (65.toDouble).==('A':Char)
// Displays output
println(result)
}
}
输出:
true
示例 #2:
// Scala program to explain the working
// of Double ==(x: Char) method
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Applying ==(x: Char) function
val result = (75.00133.toDouble).==('G':Char)
// Displays output
println(result)
}
}
输出:
false
