Currently I am developing an application which incorporates some numerical calculations. This application makes use of the MathLib Library functions. My Question is...automatic rounding, It seems anything greater than 7 significant digits is all that i can obtain. Can I achieve greater accuracy ? Thanks

Hi,

seven digits is about the limit for PocketC's 32 bit floating point values. But there is a remedy:

I developed some PocketC code to perform integer and floating point operations (+, -, *, /, comparison) with an arbitrary number of digits. It's all written in PocketC, and the source code is freely available from my website:
