floating number and LCD

[Rizwanishaq]

How i display the floating point number on the LCD.
suppose i have the 0.95 but we only send character and most of the program i found is of the character type. So how i write program in 8051 that i can display floating point number.

how i write program in 8051

Are you write program in C or in assembly?

first you need to convert the number to string using sprintf and then write it character by character.

hi,
representing a floating point no on a fixed point cpu is the sole responsibility of the programmer.cos the cpu cant understand the floating point no.its the programmers interpretation.
just keep track of the "."(decimal point) and send the character (one by one) to the lcd.
i dont see any trouble in the process.

hi,
representing a floating point no on a controller is difficult if it doesnt support the folating point numbers.so the cpu cant understand the floating point no.its the programmers interpretation.
need to find out where the decimal point should keep and place the decimal pointthere in LCD.
i dont see any trouble in the process.
