Number Parsing
This Go code demonstrates the use of the strconv
package for converting strings to various numeric types. Let's go through the code with inline comments and explanations:
Output
Explanation:
Parsing a Floating-Point Number:
strconv.ParseFloat("1.234", 64)
parses the string "1.234" to a floating-point number with a precision of 64 bits.
Parsing an Integer:
strconv.ParseInt("123", 0, 64)
parses the string "123" to a signed integer with a bit size of 64.
Parsing a Hexadecimal Integer:
strconv.ParseInt("0x1c8", 0, 64)
parses the string "0x1c8" as a hexadecimal integer with a bit size of 64.
Parsing an Unsigned Integer:
strconv.ParseUint("789", 0, 64)
parses the string "789" to an unsigned integer with a bit size of 64.
Parsing Integer using Atoi:
strconv.Atoi("135")
is a shorthand for parsing an integer usingParseInt
with base 10 and bit size 64.
Parsing an Invalid String (Results in Error):
strconv.Atoi("wat")
attempts to parse the invalid string "wat" to an integer, resulting in an error.
This code demonstrates the use of strconv
functions for converting strings to numeric types in Go. It also shows handling errors when parsing invalid strings.
