Abstract
The present invention is applicable to the field of single chip microcomputers, provides a floating point number display method applied to an 8-bit single chip microcomputer and aims to solve the problem, in the 8-bit single chip, that floating point number calculation microcomputer reduces the running efficiency of code and further influences performance of the single chip microcomputer. The method comprises: acquiring a calculation formula of a to-be-displayed floating point number; according to requirements of display precision of the to-be-displayed floating point number, performing processing of multiplying 10n on the calculation formula, wherein n is a natural number; and performing integer calculation on the calculation formula subjected to processing of multiplying 10n to obtain each bit display value of the to-be-displayed floating point number. By means of the floating point number display method applied to the 8-bit single chip microcomputer provided by the present invention, floating point calculation is simplified into integer calculation, and the display value of the floating point number with the same precision is obtained without the need for forcibly converting a variable type and floating point number calculation, so that running efficiency of code is improved, and product performance is optimized.
