VERSION
version 0.61
SYNOPSIS
use SHARYANTO::Scalar::Util qw(
looks_like_int
looks_like_float
looks_like_real
);
say looks_like_int(10); # 1, isint() also returns 1
say looks_like_int("1".("0" x 100)); # 1, isint() returns 0 here
say looks_like_int("123a"); # 0
say looks_like_float(1.1); # 1
say looks_like_float("1e2"); # 1
say looks_like_float("-Inf"); # 1
say looks_like_float(""); # 0
# either looks like int, or float
say looks_like_real(1); # 1
say looks_like_real(1.1); # 1FUNCTIONS
looks_like_int($arg) => BOOL
Uses Scalar::Util's looks_like_number() to check whether $arg looks like an integer.
looks_like_float($arg) => BOOL
Uses Scalar::Util's looks_like_number() to check whether $arg looks like a floating point number.
