Syntax
Following is the syntax for cmp() method:
cmp( x, y )
Parameters
• x -- This is a numeric expression.
• y -- This is also a numeric expression.
Return Value
This method returns -1 if x < y, returns 0 if x == y and 1 if x > y
Example
The following example shows the usage of cmp() method.
#!/usr/bin/python
print "cmp(80, 100) : ", cmp(80, 100)
print "cmp(180, 100) : ", cmp(180, 100)
print "cmp(-80, 100) : ", cmp(-80, 100)
print "cmp(80, -100) : ", cmp(80, -100)
Let us compile and run the above program, this will produce the following result:
cmp(80, 100) : -1
cmp(180, 100) : 1
cmp(-80, 100) : -1
cmp(80, -100) : 1
exp(x)
Description
The method exp() returns returns exponential of x: e x .
Syntax
Following is the syntax for exp() method:
import math
math.exp( x )
Note: This function is not accessible directly, so we need to import math module and then we need to call this
function using math static object.
Parameters
• x -- This is a numeric expression.
