The information in this article applies to:

- Pronto for Windows releases from 5.30 up to and including 5.39.

## Symptoms

The equation for certain math data-stream functions is incorrectly displayed. This problem applies to:

1) Cubic math stream function,

2) Quadratic math stream function,

3) Linear math stream function.

when one of the terms of the math function has an integer value ending in zero such as 10, 20, 50, 120 etc

For example a linear math stream function generated using the equation:

Y(x) == 10 * x + 3

has its equation displayed as

Y(x) == 1 * X + 3

The values for the data stream are however generated correctly.

## Cause

There is a bug in the number formatting routine for certain math stream functions. Integer values ending in zero have trailing zeros removed.

## Resolution

Upgrade Pronto for Windows to release 5.40 or later.
