浮點數prev_float()是一個浮點類方法,它返回浮點數的先前表示形式。
用法: float.prev_float()
參數:要傳遞的浮點值
返回:浮點數的先前表示形式。
範例1:
# Ruby code for prev_float() method
# Initializing value
a = 26.00/ 3
b = 8.0999
c = 3 + 105.003
# Printing Result
puts "previous Floating Point Number:#{a.prev_float}\n\n"
puts "previous Floating Point Number:#{b.prev_float}\n\n"
puts "previous Floating Point Number:#{c.prev_float}\n\n"
輸出:
previous Floating Point Number:8.666666666666664 previous Floating Point Number:8.099899999999998 previous Floating Point Number:108.00299999999999
範例2:
# Ruby code for next_float() method
# Initializing value
a = 26.00
b = 8.0
# Printing result
puts "previous Floating Point Number:#{a.next_float}\n\n"
puts "previous Floating Point Number:#{b.prev_float}\n\n"
輸出:
previous Floating Point Number:26.000000000000004 previous Floating Point Number:7.999999999999999
