December 31, 2023 - package main import ( "fmt" "reflect" "strconv" ) func main() { floatNumb, err: = strconv.ParseFloat("123.23", 32) fmt.Println(floatNumb) fmt.Println(reflect.TypeOf(floatNumb)) fmt.Println(err) float32Value: = float32(floatNumb) // Convert to float 32 fmt.Println(float32Value) fmt.Println(reflect.TypeOf(float32Value)) } Output: 123.2300033569336 float64 <nil> 123.23 float32 · #Golang · #Golang-examples · Categories · Javascript (6) Angular (84) Dart (116) Golang (25) Java (69) Primeng (14) Python (44) Typescript (69) Vuejs (18) Blockchain (1) Reactjs (63) Git (5) Nodejs (64) Node (1) Swift (48) Tags ·

ParseFloat accepts decimal and hexadecimal floating-point numbers as defined by the Go syntax for floating-point literals. If s is well-formed and near a valid floating-point number, ParseFloat returns the nearest floating-point number rounded using IEEE754 unbiased rounding.

July 1, 2021 - package main import ( "fmt" "strconv" ) func main() { var str = "14.2356" result, err := strconv.ParseFloat(str, 32) if err == nil { fmt.Println("The float value is :", result) } else { fmt.Println("There is an error converting string to float.") } }

October 4, 2022 - It seems i'll do that eventually. In the mean time, found ParseFloat from math/big library, but is super slow (~8x wrt strconv.ParseFloat). ... Yeah I imagine it would. ... Thanks for the suggestion. I benchmarked golang port of the simdjson against gjson and gjson was faster for my use case.

December 13, 2020 - An advance ParseFloat for golang, support scientific notation, comma separated number - parseFloat.go

A string can be converted to a float in Golang using the ParseFloat function within the strconv package.

September 15, 2025 - The 32-bit version provides approximately 7 decimal digits of precision, while 64-bit offers about 15-17 digits. WWhen bitSize=32, ParseFloat rounds the result to float32 precision; if the value is out of range, it returns ±Inf along with an ErrRange error.

September 10, 2021 - The return type of the ParseFloat() function is (float64, error), it returns the floating-point number converted from the given string. // Golang program to demonstrate the // example of strconv.ParseFloat() Function package main import ( "fmt" "strconv" ) func main() { fmt.Println(strconv.ParseFloat("123.50", 32)) fmt.Println(strconv.ParseFloat("123.50", 64)) fmt.Println(strconv.ParseFloat("-123456789.501234", 32)) fmt.Println(strconv.ParseFloat("-123456789.501234", 64)) fmt.Println() fmt.Println(strconv.ParseFloat("NaN", 32)) fmt.Println(strconv.ParseFloat("Inf", 32)) fmt.Println(strconv.ParseFloat("-Inf", 32)) }

January 26, 2026 - The strconv.ParseFloat() function in Go is used to convert a string to a floating-point number. This function takes two arguments: the string to be converted and the number of bits the floating-point number should occupy (32 or 64).

May 5, 2023 - The strconv package provides the ParseFloat function to convert a string to a float type. This function takes three arguments - the string to be converted, the bit size of the float type, and the precision of the float type.

May 19, 2020 - If a1 or a2 is well-formed and near a valid floating-point number, ParseFloat returns the nearest floating-point number rounded using IEEE754 unbiased rounding which is parsing a hexadecimal floating-point value only rounds when there are more bits in the hexadecimal representation than will fit in the mantissa. ... // Golang program to Convert // string to float type package main import ( "fmt" "strconv" ) func main() { // defining a string a1 a1 := "-2.514" // converting the string a1 // into float and storing it // in b1 using ParseFloat b1, _ := strconv.ParseFloat(a1, 8) // printing the float b1 fmt.Println(b1) a2 := "-2.514" b2, _ := strconv.ParseFloat(a2, 32) fmt.Println(b2) fmt.Println(b1 + b2) } Output:
