fixed-point number

As any processor has a fixed set of registers, there is a limit to the number of variables that can be kept in registers at any one point in the program.

寄存器的数量在每个处理器当中都是固定的，所以在程序的某个特定的位置，可以保存在寄存器中的变量的数量是有限制的。

The number is converted to the most compact of either fixed-point or scientific notation depending on the type of the number and whether a precision specifier is present.

根据数字类型以及是否存在精度说明符，数字会转换为固定点或科学记数法的最紧凑形式。

The frequency of a sound wave, perceived as pitch, is the number of compressions that pass a fixed point per unit time.
