Signature

u64 to_u64(String s, u64 fallback = 0)

Parameters

s : string to parse

fallback : value returned when s is empty or not a complete unsigned integer

return value : parsed u64, or fallback.

Parses a trimmed string as a base-10 unsigned integer.

Unlike int_val(), the whole trimmed string must be consumed by the parser. Empty strings and partially parsed values such as "42px" return the fallback.

Example

print(to_u64("7"), "\n");
