function byteTableToDouble(Table) : Number

Converts a table of bytes to a double precision (64-bit) floating point number.

Function Parameters[edit]

Parameter Type Description
Table Table A table containing the bytes to convert (least significant byte first).

Returns[edit]

Number — The resulting double precision floating point value.

Explanation[edit]

The function takes a table of bytes (e.g., {0x1F, 0x85, 0xEB, 0x51, 0xB8, 0x1E, 0x09, 0x40}) and interprets them as a 64-bit double in little-endian order.

For example, byteTableToDouble({0x1F, 0x85, 0xEB, 0x51, 0xB8, 0x1E, 0x09, 0x40}) returns 3.14.

Examples[edit]

local doubleValue = byteTableToDouble({0x1F, 0x85, 0xEB, 0x51, 0xB8, 0x1E, 0x09, 0x40})
print(doubleValue) -- Output: 3.14
