Description
Used to multiply a floating point value v1 by the number 2 raised to the v2 power. This is called a load exponent. v2 should be an integer.
(number) = math.ldexp(v1,v2)
Returns v1*2^v2.
Parameters
v1: (number) a floating point value
v2: (number) an exponent
Return values
Returns (number) the load exponent result
Example
local m, n = math.frexp(16.4)
print("mantissa", m, "exponent", n)
print(m*2^n)
local r = math.ldexp(0.5125, 5)
print("load exponent result", r) -- 16.4
Note
math.frexp is the inversed operation.
