Perl | sin() Function

Last Updated : 25 Jun, 2019

This function is used to calculate sine of a VALUE or $_ if VALUE is omitted. This function always returns a floating point.

Syntax: sin(VALUE) Parameters: VALUE in the form of float Returns: Function returns sine of VALUE.

Example 1:

Perl

#!/usr/bin/perl

# Calling sin() function
$var = sin(5);

# Printing value for sin(5)
print "sin value of 5 is $var";

Output:

sin value of 5 is -0.958924274663138

Example 2:

Perl

#!/usr/bin/perl

# Calling sin() function
$var = sin(9);

# Printing value for sin(9)
print "sin value of 9 is $var";

Output:

sin value of 9 is 0.412118485241757
