Converts a Boolean
, String
, or Number
to its byte value.
byte()
converts a value to an integer (whole number) between -128 and 127. Values greater than 127 wrap around while negative values are unchanged. For example, 128 becomes -128 and -129 remains the same.
The parameter, n
, is the value to convert. If n
is a Boolean, as in byte(false)
or byte(true)
, the number 0 (false
) or 1 (true
) will be returned. If n
is a string or number, as in byte('256')
or byte(256)
, then the byte value will be returned. Decimal values are ignored. If an array is passed, as in byte([true, 123, '456'])
, then an array of byte values will be returned.
Note: If a value can't be converted to a number, as in byte('giraffe')
, then the value NaN
(not a number) will be returned.
