ESBCalc is a free Scientific Calculator for Windows.

Features:

Infix Notation, Brackets, Scientific Functions (Trigonometric, Hyperbolic, Logarithmic – including Base 10, Base 2 & Natural – plus more), Memory, Paper Trail, Result History List, and more.

ESBCalc includes support for Prefix functions so that to evaluate log (10) you can enter log 10 rather than 10 log, which is the default behaviour.
