gpuLm.defaultTol: Function to switch tolerance depending on precision
Description
This function was written by Mark Seligman at Rapid Biologics,

The function gpuLm.fit calls this function
to determine a default tolerance. So gpuLm.defaultTol should
not need to be used directly.
Usage
gpuLm.defaultTol(useSingle = TRUE)
Arguments
useSingle
logical. If TRUE, a tolerance will be returned appropriate
for single precision arithmetic. If FALSE, a tolerance will be returned
appropriate for double precision arithmetic.
Value
a floating point number representing a tolerance to be used by gpuLm.fit
