Type Conversion Functions

The following type conversion functions are provided by Sprig:

• atoi: Convert a string to an integer
• float64: Convert to a float64
• int: Convert to an int at the system's width.
• int64: Convert to an int64
• toString: Convert to a string
• toStrings: Convert a list, slice, or array to a list of strings.

Only atoi requires that the input be a specific type. The others will attempt to convert from any type to the destination type. For example, int64 can convert floats to ints, and it can also convert strings to ints.

toStrings

Given a list-like collection, produce a slice of strings.

list 1 2 3 | toStrings

The above converts 1 to "1", 2 to "2", and so on, and then returns them as a list.
