Perl is a context-based language. It doesn't do its work according to the data you give it. Instead, it figures out how to treat the data based on the operators you use and the context in which you use them. If you do numbers sorts of things, you get numbers: # numeric addition with strings: my $sum = '5.45' + '0.01'; # 5.46

If you do numbers sorts of things, you get numbers: # numeric addition with strings: my $sum = '5.45' + '0.01'; # 5.46 Perl中的int()函数返回给定值的整数部分。如果未提供值，则返回$_。注意$_是默认输入，在这种情况下为0。 int()函数不进行舍入。为了将值四舍五入为整数，使用sprintf。 2019-02-12 · For example, if there is a string “1234” and after converting it to int data type the output will be an integer 1234. Conversion of string to integer in Perl has many ways. One is to use Typecasting , while the other one involves use of ‘ sprintf ‘ function. Se hela listan på tutorialspoint.com perl int()函數，int()函數學習例子，int()函數實例代碼，int()函數教學等 This is arguably the most correct answer, since Scalar::Util hooks into the Perl API to actually ask Perl whether it thinks the variable looks numeric. Thus, for the common task of avoiding 'numeric' warnings, this will always work.

exception is when you 'use integer'. Se hela listan på tutorialspoint.com That's because in each iteration of the loop, the current string is placed in $_, and is used by default by print. Here are the places where Perl will assume $_ even if you don't specify it − Various unary functions, including functions like ord and int, as well as the all file tests (-f, -d) except for -t, which defaults to STDIN. Perl applies the format to each integer in turn, then joins the resulting strings with a separator (a dot .

Floating-Point Types. Perl supports platform-native floating-point as scalar values; in practice this usually means IEEE 754 double precision.. Exact Types. Perl can also store decimal numbers as strings, but the builtin arithmetic operators will convert them to integer or floating-point values to perform the operation.
