Perl Numeric Scalars
A scalar is most often either a number or a string. Following example demonstrates the usage of various types of numeric scalars −
Example
#!/usr/bin/perl $integer = 200; $negative = -300; $floating = 200.340; $bigfloat = -1.2E-23; # 377 octal, same as 255 decimal $octal = 0377; # FF hex, also 255 decimal $hexa = 0xff; print "integer = $integer\n"; print "negative = $negative\n"; print "floating = $floating\n"; print "bigfloat = $bigfloat\n"; print "octal = $octal\n"; print "hexa = $hexa\n";
Output
This will produce the following result −
integer = 200 negative = -300 floating = 200.34 bigfloat = -1.2e-23 octal = 255 hexa = 255
