# Zig ParseNumber

ParseNumber returns a struct has a `parse` member that takes a slice and returns a T.

```
pub fn ParseNumber(comptime T: type) type {
    return struct {
        fn parse(str: []const u8) !T {
	    ...
	}
    }
}
```


## Examples

```
test "ParseNumber.parseF32" {
    const parseF32 = ParseNumber(f32).parse;
    var vf32 = try parseF32("123.e4");
    assert(vf32 == f32(123e4));
}
```
