Editing EDSAC (section)

===Application software===
The subroutine concept led to the availability of a substantial subroutine library. By 1951, 87 subroutines in the following categories were available for general use: [[floating-point arithmetic]]; arithmetic operations on [[complex number]]s; checking; division; [[exponentiation]]; routines relating to functions; [[differential equation]]s; special functions; [[power series]]; [[logarithm]]s; miscellaneous; print and layout; [[Numerical integration|quadrature]]; read (input); ''n''th root; [[trigonometric functions]]; counting operations (simulating [[do while loop|repeat until loops]], [[while loop]]s and [[for loop]]s); [[probability vector|vectors]]; and [[matrix (mathematics)|matrices]].

The first [[assembly language]] appeared for the EDSAC, and inspired several other assembly languages:
