Numbers

Literals

V supports the following kinds of integer literals:

Literals can use _ as a delimiter:

million := 1_000_000 // same as 1000000 three := 0b0_11 // same as 0b11

You cannot use more than one delimiter in a row.

V supports the following kinds of floating point literals:

1.0 - standard notation
1. - notation with zero decimal part
.1 - entry with zero integer part
1e10 - notation with exponent
- 1e+10 - positive exponent (by default
- 1e-10 - negative exponent

As with integer literals, floating point numbers can use _ as a delimiter:

float_num := 3_122.55 // same as 3122.55

By default, if you don't specify a type explicitly, then literals will be of type int or f64 depending on whether it is an integer or a float.

a := 123 println(typeof(a)) // int b := 3.14 println(typeof(b)) // f64

If you want to use a different type, then you can use a casting:

a := i64(123) println(typeof(a)) // i64 b := f32(3.14) println(typeof(b)) // f32
