Example 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)

Output:

0.16576849565979213

Example 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)
