红宝石 |数学 erfc()函数
Ruby 中的erfc()函数返回 x 的互补误差函数。它接受 [-inf, +inf] 范围内的值并返回 [0, 2] 范围内的值。
Syntax: Math.erfc(value)
Parameter: The function takes the value whose complementary error function is to be returned.
Return Value: The function returns the complementary error function.
示例 1 :
# Ruby program for erfc() function
# Assigning values
val1 = 0.98
val2 = -0.9
val3 = 6
val4 = 1
# Prints the erfc() value
puts Math.erfc(val1)
puts Math.erfc(val2)
puts Math.erfc(val3)
puts Math.erfc(val4)
输出:
0.16576849565979213
1.7969082124228322
2.1519736712498916e-17
0.15729920705028513
示例 2 :
# Ruby program for erfc() function
# Assigning values
val1 = 0.67
val2 = -0.12
val3 = 2.4
val4 = 89
# Prints the erfc() value
puts Math.erfc(val1)
puts Math.erfc(val2)
puts Math.erfc(val3)
puts Math.erfc(val4)
输出:
0.3433722976996949
