But for small values of x , log(1 + x) is approximately x , and so log(1+x)/x is approximately 1 . A string is higher precision than a double (e.g. For numbers that lie between these two limits, you can use either double- or single-precision, but single requires less memory. For this reason, it's not clear to me why you would have exact tests on the former; they should have a tolerance. vpa provides variable precision which can be increased without limit.. For higher precision, use the vpa function in Symbolic Math Toolbox™. The Mantissa . If you have ever worked with the double values when you need precision, you might have came across a weird issue where you lost the precision of your value with a very little number. a double is probably 64 bits, with maybe 48 bits of precision. dot net perls.
