Two digits after the decimal point in a real number in Pascal

Question

So for an example i have a real number let's say 17.4578 but i want to display it in pascal with only two digits after the point so it's 17.45. What do i write in my program?

@LURD - that would produce `17.46` . Not sure if that's important to the OP. — , Jan 05 '17 at 16:28
According to Standard Pascal (ISO/IEC 7185:1990) a width specifier must be greater than or equal to one. — Stuart, Jan 05 '17 at 23:13

Write(17.4578:0:2)

Will display number 17.46
Generally, arguments look like this → Value : field_width : decimal_field_width

This would work. However, if this is the last line of code always remember a readln at the end.

    Writeln(17.4578:0:2)

This would lead to 17.46 because it rounds up as it is followed by a 7.

Hope this helps
