Euphoria有一个库例程,可将日期和时间返回到您的程序。
date()方法返回由八个原子元素组成的序列值。以下示例对其进行了详细说明-
#!/home/euphoria-4.0b2/bin/eui
integer curr_year, curr_day, curr_day_of_year, curr_hour, curr_minute, curr_second
sequence system_date, word_week, word_month, notation,
curr_day_of_week, curr_month
word_week = {"Sunday",
"Monday",
"Tuesday",
"Wednesday",
"Thursday",
"Friday",
"Saturday"}
word_month = {"January", "February",
"March",
"April",
"May",
"June",
"July",
"August",
"September",
"October",
"November",
"December"}
-- Get current system date.
system_date = date()
-- Now take individual elements
curr_year = system_date[1] + 1900
curr_month = word_month[system_date[2]]
curr_day = system_date[3]
curr_hour = system_date[4]
curr_minute = system_date[5]
curr_second = system_date[6]
curr_day_of_week = word_week[system_date[7]]
curr_day_of_year = system_date[8]
if curr_hour >= 12 then
notation = "p.m."
else
notation = "a.m."
end if
if curr_hour > 12 then
curr_hour = curr_hour - 12
end if
if curr_hour = 0 then
curr_hour = 12
end if
puts(1, "\nHello Euphoria!\n\n")
printf(1, "Today is %s, %s %d, %d.\n", {curr_day_of_week,
curr_month, curr_day, curr_year})
printf(1, "The time is %.2d:%.2d:%.2d %s\n", {curr_hour,
curr_minute, curr_second, notation})
printf(1, "It is %3d days into the current year.\n", {curr_day_of_year})
这会在标准屏幕上产生以下结果-
Hello Euphoria!
Today is Friday, January 22, 2010.
The time is 02:54:58 p.m.
It is 22 days into the current year.
time()方法返回一个原子值,该原子值表示自固定时间点以来经过的秒数。以下示例对其进行了详细说明-
#!/home/euphoria-4.0b2/bin/eui
constant ITERATIONS = 100000000
integer p
atom t0, t1, loop_overhead
t0 = time()
for i = 1 to ITERATIONS do
-- time an empty loop
end for
loop_overhead = time() - t0
printf(1, "Loop overhead:%d\n", loop_overhead)
t0 = time()
for i = 1 to ITERATIONS do
p = power(2, 20)
end for
t1 = (time() - (t0 + loop_overhead))/ITERATIONS
printf(1, "Time (in seconds) for one call to power:%d\n", t1)
这产生以下结果-
Loop overhead:1
Time (in seconds) for one call to power:0
欣快感提供了一系列方法,可帮助您操纵日期和时间。在Euphoria库例程中列出了这些方法。
