Assigning real to integer

[john]

Is there any way to assign a real variable to an integer variable?

Thanks.

Look for the definitions of the standard functions 'trunc' or 'round' in the
documentation for the Pascal implementation that you are using.

I recommend that if you wish to learn how to program in Pascal that you
acquire, and read, a copy of the 'Pascal User Manual and Report' by Kathleen
Jensen and Niklaus Wirth if you have not already done so.

6.7.6.3 Transfer functions

trunc(x)

From the expression x that shall be of real-type, this function
shall return a result of integer-type. The value of trunc(x)
shall be such that if x is positive or zero, then 0 <= x -
trunc(x)
< 1; otherwise -1 < x <= x - trunc(x). It shall be an error if
such
a value does not exist.

Examples:
trunc(3.5) {yields 3}
trunc(-3.5) {yields -3}

round(x)

From the expression x that shall be of real-type, this function
shall return a result of integer-type. If x is positive or zero,
round(x) shall be equivalent to trunc(x+0.5); otherwise, round(x)
shall be equivalent to trunc(x-0.5) It shall be an error if such
a value does not exist.
