TRINT

Syntax TRINT (x)
Location TRIPRODRO

The function TRINT gives the integer part of a floating point number, it differs from INT for negative numbers only: INT always returns the next lowest integer, this is the same as the integer part for positive numbers; however below zero INT always returns one less than TRINT. For example:

INT(-PI)

will return -4 and:

TRINT(-PI)

will return -3.

CROSS-REFERENCE

The fact that:

x = TRINT(x) + FRACT(x)

can be exploited to substitute one of the two functions by the other, for example:

100 DEFine FuNction MYTRINT(x)
110   RETurn x - FRACT(x)
120 END DEFine MYTRINT
