If y is not a member of the set of floating-point numbers, we say that x is not representable in the floating-point number system. This can happen if x is too large, which is called overflow error; or if the absolute value of x is too small, which is called an underflow error. In Matlab , numbers are typically represented in a floating-point representation conforming to a standard established by the Institute of Electrical and Electronics Engineers (IEEE) in 1985. In the IEEE double-precision standard used by Matlab , there are 53 bits in the mantissa and 11 bits in the exponent, for a total of 64 bits to represent a scalar number. This provides a range of values extending from 10 308 to 10 308 . A single-precision representation is usually considered to be a 32-bit representation, but this is not supported by Matlab . Two Matlab functions, realmax and realmin

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
