REBOL 3 Functions: to

Description

Every datatype provides a TO method to allow conversions from other datatypes. The to-binary, to-block, and all other to- functions are mezzanine functions that are based on this TO function.

Here are a few examples:

probe to file! "test.r"
%test.r

probe to path! [a b c]
a/b/c

The TO function lets the target datatype be specified as an argument, allowing you to write code such as:

flag: true
value: to either flag [integer!][decimal!] "123"
print value
123

The conversions that are allowed depend on the specific datatype. Some datatypes allow special conversions, such as:

print to integer! false
0

print to integer! true
1

print to logic! 1
true

print to time! 600  ; # of seconds
0:10
