Write a program in Fortran 90 to solve the equation:

Calculate the function values and display the result in the form of a table. When performing calculations, provide for handling exceptional situations, for example, division by zero, calculating an even root of a negative number, etc.

when x changes from -1 to 1 in steps of 0.1, and y from -1.25 to 0.25 in steps of 0.05

**lg:log

z(x,y)=ch(2y/x)cos(x/y)lg(x+y)
