REBOL 3 Functions: subtract

subtract value1 value2

Returns the second value subtracted from the first.

Arguments:

value1 [scalar! date!]

value2 [scalar! date!]

Description

Note: The + operator is a special infix form for this function.

Many different datatypes support subtraction. Here are just a few:

print subtract 123 1
122

print subtract 1.2.3.4 1.0.3.0
0.2.0.4

print subtract 12:00 11:00
1:00

print subtract 1-Jan-2000 1
31-Dec-1999

When subtracting values of different datatypes, the values must be compatible. Auto conversion of the values will occur into the datatype that has the most expansive representation. For example an integer subtracted from a decimal will produce a decimal.
